To me this test really shows how important it is to plan your build on any engine. Proper part matching is a huge key to making good high horsepower especially on budget. Like your test shows quality high dollar parts won't work well a stock cam. Funny thing is a stock engine with factory heads and better cam and intake and headers, then you've got a foundation that will just keep getting better and better.
I have the same combo but in A 406.I love the HP and torque but I wanted to add A little more.All I need is 6-7 pounds wow.Definitely looking at the Torquestorms now.
Those guys at torquestorm are idiots. I went with vortech and I'm happy that I did. The guys from torquestorm say that the holley sniper throttle body won't flow air under boost. My vortech runs amazing blowing through at 9.5psi. I still get emails from them. They just had a huge article talking about cams. NA cams won't work with their supercharger systems. One of their customers had a car running in the 11s NA. They added a torquestorm setup and ran 14s.. then changed the cam and the following weekend ran 8.90s with no other changes. That's an awful lot of bullshitting to me. I'd stay away. They also told me to just buy an aftermarket front accessory drive for a few grand rather than tell me if my factory gm front accessories will work with one of their superchargers. I've got a lot of money invested in my motor, but I don't want to buy a whole pulley setup of I don't have to. They also state in their email that an NA cam can't handle the extra airflow that their centrifugal superchargers add at idle. Centrifugal superchargers have a rising boost curve. At idle there's basically zero boost. My front accessories work great with my stock front accessories. The alternator bracket changed and so did the power steering bracket. If you want to run one of their superchargers, that's fine, but don't listen to their mis-informed bullshit. I'm running a vortech v3 si trim supercharger. It's a universal carbureted kit for sbc. I'm running holley sniper tbi efi on it. The tuning was super easy to add fuel and pull timing under boost.. and with my combination, the truck pulls hard from idle on. Vortech says it's capable of 775hp. After that, you could look at a y or t trim. Or procharger. I'd stay away from torquestorm tho. Good luck man.
Wanted to add a "all cylinder heads are turbo cylinder heads" comment since it was brought up. Consider that stock Grand National heads don't even flow 150CFM on the intake and have been deep into the 11s if not the 10s in a G-body. If you consider that they have 6 cylinders not 8 you'd be looking at a flow of 112 CFM on a V8! Obviously that was done with race gas and high boost, but if you can get E85 it really makes one question if they really need to worry about head flow on a moderate power street engine. I can tell you the AMC 258 I'm sticking a T66 on will likely have a 4.0L head with a valve job to start with. If the guides weren't shot I wouldn't even go that far. I keep thinking I want to do port work on it then keep thinking better of it.
I just put some 1.7 scorpion roller rockers on a stock 350 truck cam. 13% more valve lift? It can't hurt! Brought me from. 385"/.402" to .437"/.456". The tune didn't change much. Onesies and twosies on the stock tbi efi. I plan to eventually install them on a Comp xfi252hr roller cam and get .585"/.580" lift on my vortech supercharged 355. With the recommended 1.6 rockers, that cam produces .550"/.546" lift.

I damn well know a cam is capable of making even more power with forced induction. But I am always here to support Richard because there is not another guy with. 1 more knowledgeable 2 more PROVEN testing and access to a Dyno and more motor combinations then we can imagine, and 3 more interaction with his audience that dosen't have millions of subscribers. I know plenty of podcasters who no less about cars and don't get the recognition that Richard deserves. If Scotty Kilmer can build the largest single man stand alone channel how Richard can't angers and confuses me. I like both guys but scotty is clickbait crap these days because one day he says something is great then the next day he says it's crap. Richard builds what his fans want to see and SHOWS YOU EXACTLY what is going to happen and what you can expect performance wise no opinion just consistsproven results. The uncrowned king👊🏻 On a different note I have an E90 6.2 build of my dreams, hit me up have parts listed below, I have everything to do the swap ( trans, all mounts, stand alone, and built 8.8 and cage) the block is stock and stripped down. So cam, possibly heads dependingon price , injectors,, fuel pump, fuel cell, aluminum pistons, and single plane. God bless everyone who read this.🇺🇸👊
If you start with a very wrong camshaft, and then install the best possible camshaft, maybe. If the engine starts out with a camshaft that is reasonably correct for the engine combination, you won't find one worth 200 horsepower, by itself.
Always the best money spent on any hotrod project,,, Although I find it 😎 best to get your stickers out of the box the parts come in.... Ain't it just ain't it. thanks
Great video. I have a question I plan doing a new flat tappet cam and lifter’s can install it a not start the motor until I put the heads on and then put in the car. Is there a time frame before the cam lube is not affective upon when I start for the time. Thanks
I swapped my intake cam, the most aggressive from the ones that came with all the next generations of my engine. And my butt dyno says it gained not more than 20 :)
I had a 1974 Chevy El Camino, and I had a 350 motor in it, so I am curious how much boost can this 383 handle, but I think this is a forged crankshaft, connecting rods and pistons right? I am curious if this 383 had a 4 bolt main not forged maybe cast iron how much boost could it handle thank you.
Larger rocker ratio amplifies the valve acceleration and should give more airflow in the same duration (time), so I am betting on the rocker ratio to win.
the effect of a change in rocker ratio is not universal. it doesn't always add or subtract power, sometimes it does nothing, other times (without adequate spring pressure) it initiates valve float
Right, it's interesting stuff, my 4.3 is getting tired.... not really wanting to build up to eight, of course with minimal cost, still basic transportation, not a Hot Rod.... thanks I have learned a great deal with you and all of your subscribers 😊 keep up the good work , JD
Glyptal painted internal engine surfaces to imagine helping that hot oil drain away faster for a solid 0.01 HP gain (also imagined). LOL those were the days.
Hey Richard can you do a dyno comparo with the Summit sbc cam firing order change camshaft? See if you can find the same spec sbc standard firing order cam to compare.
I really would be curious to see I had to combination would run on in E85 carburetor instead of running on 100 octane was a lot of racers going to E85 might be worth seeing what the numbers would bring out and have this engine would be a perfect combination for low budget race car if and when you get a chance have a great day
You're running this on E85 combination or likely looking at what 650 out the door I believe a summit stock 383 her run close to 500 what a 383 combination I would be happy with running about 580 to 6:50 to be able to run 11 second bracket or a high 10 without using nitrous my brother at the moment is running in 78 Malibu with a 355 small block on an E85 carburetor and a title it was running 585 to the rear wheels without nitrous and the best PT that I so far I've seen was 1102 at 121 has plans for this year are to build a 383 small block ordered from Summit what's it called to run all 11 doing a high 10 without running nitrous or no supercharger he just wants to run nicely aspirated I don't think you'll get to 650 horsepower
🥝✔️ ❤️ Richard Holdener boost ratio increase divided by the naturally aspirated boost. At an effective average of a 1.41:1 boost ratio, that's less 7.5 pounds of effective boost. If the gain over the stock 252 degree cam verses the 294 Comp Cam was 156 HP gross naturally aspirated Cam A versus Cam B, then it'll be a 220 HP gain under the Patented Holdener Boost Ratio. PS. Have a Nice Day. P.P.S. Am I learning anything, or do I need remedial schooling again?
It's TOTAL click bait Richard, there isn't a single person on planet earth that's going to spend the thousands of dollars to build a bottom end, top end, and a blower and then not spend the few hundred bucks on an aftermarket cam. It's not even "just a cam swap" it's a whole build. Everything about this is the epitome of click bait by definition lol. 😆
@@richardholdener1727 I'm probably butchering this expectation, but it sounds like he replaces the power valve with a pwm solenoid and has an engine map sensor to control vacuum bread off and has inputs from a wide band O2 sensor to reach a desired A/F ratio, he has a few videos on it on his RUclips channel.
I'm still learning this stuff and am wondering if this would have the same effect on my combo? I have a similar 383 short block, but only have forged pistons. I'm currently using a flat tappet cam with 234/234@ .050 and .480 lift and 114lsa.

@@richardholdener1727 Hi Richard.. I have sbc383 gen1, with 144 B&M Blower. 8.5 comp. ratio. Can I run 10psi with pump gas? With this cam. Thank you..:)
Here's an odd one, I'd love to see a comparison of two setups with equal lift at the valves but different lobe lift and rocker ratio. For example .575" valve lift with a 1.5 rocker and a .383" lobe cam vs 1.6 rocker and .359" lobe cam. Does it do anything measurable? Is there a larger rocker ratio to push the example farther like a 1.65 or 1.7?
I just installed a set of 1.7 ratio scorpion roller rockers on my 92 c1500. Regular old 350 motor with 267k miles. It added 13% more valve lift with essentially the same duration. You can find different ratio rockers. 1.5 and 1.6 are most common, but you can find higher ratios for racing or lower ratios for easier flat tappet cam break-in. I think I've seen 1.2 ratio for break in. I don't know if they make 1.8 for sbc. I'm sure if your pockets are deep enough, someone will make a set. Lol. The 1.7s were about double the price that I paid for my 1.5/1.6 roller rockers.
@@EricErnst I've got Comp Ultra Pro Magnum 1.52 in my supercharged small block combo. I'm curious to see if there's a measurable difference in performance when using a small cam and larger ratio rocker vs a large cam and small ratio rocker. There's plenty of examples of just changing rocker ratio but that's not my question.
@@EricErnst Any lift will help the stocker cam out. A stock LT-1 cam from a Y/F body is a huge improvement on that engine too or the Elgin 210/215. Then again, you don't have to crack the engine open to do the rockers etiher.
@@thetriode I've got an extra xfi252hr cam lying around. It's 252⁰/264⁰ advertised, 202⁰/212⁰@.050". 114⁰lsa. .550"/.546" lift with 1.6s. Very short duration for great off-idle torque. The tbi heads flow terrible and the stock tbi can barely keep up with a stock 350. If I used a bigger cam, the heads would run out of air as the cam is coming to life.. and the big cam would kill low end torque. I'm going to bump up fuel pressure on stock injectors and try to get 315hp worth of fuel out of the pair of stock injectors. 315hp out of a 350 is pathetic, but with stock tbi, I think it will be a fun project. The stock cam in those trucks was something like 165⁰/175⁰@.050" with .385"/.402" lift. No wonder they only rated the motors at 190hp!
You made this sound like just changing a stock cam is going to increase engine by 200hp. Said nothing in intro or header about the engine already being blown. Thought somewhere you were going to get to the NA gains. Thats why I watched the whole video is because sometimes you have different tests throughout the video. Was waiting for the one described in the header and beginning of the video. 200hp gain with a cam swap on a blown engine is not a big deal.
Well yup, turns out to be clickbait right off the rip! 200hp cam swap,,,WITH BOOST! People be clicking seeing 200hp cam swap thinking naturally aspirated! But yes, car guys are going to more than likely still watch it.
@@richardholdener1727 yes I seen that, I wasn't quite clear with my statement. Meant to say having a base line engine with a forced air induction system can have more opportunity for power increase because of the ample supply of air. Being the heads are your biggest obstacle at that point, anything with the valve train could be huge ! Small cam to larger (especially one designed for the application) could make obviously as you have showed drastic improvements
ruclips.net/video/72hVhcBOyPo/видео.html Video I was talking about (and shamelessly plugging.) They make a kit to do this but you don't really need it if you have a grinder and patience. This is for a 700R4, but the TH350 governor is the same. In fact, I believe the lightest weight one is from a TH350. Something being click bait vs having real and usable info in it are two things that aren't mutually exclusive. Someone may have stuck a ton of parts on a stock or mildly cammed engine and wonder why they weren't making any power. Such a piece of info could be extremely helpful to them. Testing in a systemic and scientific nature tells you where bottlenecks are.
So........ This kinda Blows up the never ending BS Question about the needs of the purpose of running a camshaft for boosted applications only! 🙄 The argument is that a camshaft somehow has the ability to determine atmospheric pressures and do something to improve the overall performance of its profiles for boosted and naturally aspirated conditions!?!? Really these cam profiles are different, but they're not something that is necessarily needed nor will they always improve the power output by running a "Boosted Profile" camshaft! There's lots of theories about this topic and some of these things do apply to specific boost situations.......but not all boosted situations apply. If you're running a turbocharger and take advantage of your exhausting of your engines exhaust pressures to rise, absolutely yes Sir it would be a probable benefit to run a specialized boost camshaft for turbocharger applications! The positive displacement of anything like a supercharger though....... here's where things differ. Being your compressor isn't relying on certain conditions for building boost quicker and easier than something with a positive displacement driven system, the camshaft really is not going to hurt or benefit the boosting capacity of your engine. Being you may not specifically need so much duration @ .050" to achieve the numbers you are looking for without having to deal with high stall speeds from having a big duration cam profile, you can actually get away from the chop factory and still get more air packed tighter into your cylinders. By utilizing a higher lift and a reduction in the duration for say street purposes, by making up for pulling out of the duration and building higher lift and this could easily be done with ratio rockers as well if you don't have the money to make a cam swap? Springs and a higher ratio rocker arm is going to definitely complement your boost and increase your overall output without the need for changing the camshaft profile. This is why you can actually boost almost anything you want. Will it be efficiently perfect with say a stock camshaft profile and additional lift? Probably not, but it's worth the price of doing it for the gains that you will feel and see on the dyno. Comes down to getting as much air stuffed into your cylinders as easily as possible so by increasing the lift and leaving out the needs for bigger duration, this is very possible. This is why many forced induction engines stock to street/strip, you are sometimes fooled by the sleeper effects of not hearing any lump in the camshaft department, and take the bait as it's not going to be a very fast vehicle LMAO! I made this mistake 1 time with a worked Buick GN and had a 10 sec G body 442 running a aluminum big valved heads, roller cam'ed 406 SBC with 12" slicks and got spanked by this grandma sounding grocery getter V6! It was definitely worked over, had heads cam, converter and computer work done! But you'd never know you were pulling up along side a mid 9 second car! LoL lesson learned in under 10 seconds really almost 6 seconds as I got him off the line and about halfway thinking wow thats easier than I was thinking??? SMFH! But soon as this thought passed my mind, LoL well so did his car! 👋 He was able to catch up about 2 car lengths and then surpass me at the end...... That was the last time I laughed at how weird sounding those Buick V6's sounded under load at high RPM'S! And no longer looked down at small displacement engines with a boost adder of some sorts.

Back in the 80s we knew the limit of the 350 chevy blocks so we didn't push them much past 600 hp.
I damn well know a cam is capable of making even more power with forced induction. But I am always here to support Richard because there is not another guy with. 1 more knowledgeable 2 more PROVEN testing and access to a Dyno and more motor combinations then we can imagine, and 3 more interaction with his audience that dosen't have millions of subscribers. I know plenty of podcasters who no less about cars and don't get the recognition that Richard deserves. If Scotty Kilmer can build the largest single man stand alone channel how Richard can't angers and confuses me. I like both guys but scotty is clickbait crap these days because one day he says something is great then the next day he says it's crap. Richard builds what his fans want to see and SHOWS YOU EXACTLY what is going to happen and what you can expect performance wise no opinion just consistsproven results. The uncrowned king👊🏻 On a different note I have an E90 6.2 build of my dreams, hit me up have parts listed below, I have everything to do the swap ( trans, all mounts, stand alone, and built 8.8 and cage) the block is stock and stripped down. So cam, possibly heads dependingon price , injectors,, fuel pump, fuel cell, aluminum pistons, and single plane. God bless everyone who read this.🇺🇸👊
thnx-I just provide the info
Currently running a 355 10.75:1 afr195 street and a Howard's big daddy rattler....I think i need this camshaft 🤣🤣🤣
If you start with a very wrong camshaft, and then install the best possible camshaft, maybe.
If the engine starts out with a camshaft that is reasonably correct for the engine combination, you won't find one worth 200 horsepower, by itself.
congrats-you got the point I was trying to make in the video
Hells bells....
My friend gained 100 HP just by putting stickers on his quarter glass.
Always the best money spent on any hotrod project,,, Although I find it 😎 best to get your stickers out of the box the parts come in.... Ain't it just ain't it. thanks
Great video. I have a question I plan doing a new flat tappet cam and lifter’s can install it a not start the motor until I put the heads on and then put in the car. Is there a time frame before the cam lube is not affective upon when I start for the time. Thanks
the right cam lube stays on almost indefinitely
great test
I swapped my intake cam, the most aggressive from the ones that came with all the next generations of my engine. And my butt dyno says it gained not more than 20 :)
I had a 1974 Chevy El Camino, and I had a 350 motor in it, so I am curious how much boost can this 383 handle, but I think this is a forged crankshaft, connecting rods and pistons right? I am curious if this 383 had a 4 bolt main not forged maybe cast iron how much boost could it handle thank you.
Bro the 2 guys arguing 😂 like the 5.3 camp and 6L camp arguing in your other video 😂🤣
exactly
How about mild motor comparison with just rocker arm swap 1.5 vs 1.6 vs 1.7?
Larger rocker ratio amplifies the valve acceleration and should give more airflow in the same duration (time), so I am betting on the rocker ratio to win.
the effect of a change in rocker ratio is not universal. it doesn't always add or subtract power, sometimes it does nothing, other times (without adequate spring pressure) it initiates valve float
Lol love this dude
Wait, are you saying that you ended up with a 383 SBC that produced 540 hp NA that idled like a stock grocery getter????
Damn, I want one.
me too
@@richardholdener1727 OH, I see where my mistake was, I should have watched it again before commenting.
I'm sorry.
Now talk about this with a six 4.3 Chevrolet motor you'll find in a C10 or Blazer 2000
arp bolts, turbo and nitrous- there ya go
JD John He's already done one with a TorqueStorm designed for a 350. Since the front accessories are the same, it bolted right up.
@@melvinpinkard5333 yeah I think he did a few videos on the 4.3
Right, it's interesting stuff, my 4.3 is getting tired.... not really wanting to build up to eight, of course with minimal cost, still basic transportation, not a Hot Rod.... thanks I have learned a great deal with you and all of your subscribers 😊 keep up the good work , JD
Good one
The most reliable high compression supercharged stroker engine possible?
to finish your statement-"need octane".
Richard really can’t imagine having a small cam
Almost identical down to the number on my 383 only I do not have boost
All cams are turbo cams, but some are TURBO cams.
Glyptal painted internal engine surfaces to imagine helping that hot oil drain away faster for a solid 0.01 HP gain (also imagined).
LOL those were the days.
You don't want large valve over lap on eny blower engine. But lots of pressure you will get power what ever 😅
overlap is fine with boost
Im curious what the hp limits are for a stock N/A engine say a 400 or 350 w factory heads and intake
look at Stock Eliminator motors
Hey Richard can you do a dyno comparo with the Summit sbc cam firing order change camshaft?
See if you can find the same spec sbc standard firing order cam to compare.
firing order does not change power
But....is that XE294 a turbo cam ? Regular viewers know the answer.👍
COULD BE
Good Information here.. !
Matched parts matter! Was that intake as cast?
yes
@@richardholdener1727 Nice!
I really would be curious to see I had to combination would run on in E85 carburetor instead of running on 100 octane was a lot of racers going to E85 might be worth seeing what the numbers would bring out and have this engine would be a perfect combination for low budget race car if and when you get a chance have a great day
e85 adds 25-30 hp
You're running this on E85 combination or likely looking at what 650 out the door I believe a summit stock 383 her run close to 500 what a 383 combination I would be happy with running about 580 to 6:50 to be able to run 11 second bracket or a high 10 without using nitrous my brother at the moment is running in 78 Malibu with a 355 small block on an E85 carburetor and a title it was running 585 to the rear wheels without nitrous and the best PT that I so far I've seen was 1102 at 121 has plans for this year are to build a 383 small block ordered from Summit what's it called to run all 11 doing a high 10 without running nitrous or no supercharger he just wants to run nicely aspirated I don't think you'll get to 650 horsepower
I gained 500hp by swapping out my 0 lift cam
Lol. Yeah gotta watch now!!
🥝✔️ ❤️ Richard Holdener boost ratio increase divided by the naturally aspirated boost. At an effective average of a 1.41:1 boost ratio, that's less 7.5 pounds of effective boost. If the gain over the stock 252 degree cam verses the 294 Comp Cam was 156 HP gross naturally aspirated Cam A versus Cam B, then it'll be a 220 HP gain under the Patented Holdener Boost Ratio. PS. Have a Nice Day. P.P.S. Am I learning anything, or do I need remedial schooling again?
It's TOTAL click bait Richard, there isn't a single person on planet earth that's going to spend the thousands of dollars to build a bottom end, top end, and a blower and then not spend the few hundred bucks on an aftermarket cam. It's not even "just a cam swap" it's a whole build. Everything about this is the epitome of click bait by definition lol. 😆

Hey random question have you tried thunderhead 289s electronic carb tuner yet? The one he runs with his lawnmower carb on his maverick.
I'm not familiar
@@richardholdener1727 I'm probably butchering this expectation, but it sounds like he replaces the power valve with a pwm solenoid and has an engine map sensor to control vacuum bread off and has inputs from a wide band O2 sensor to reach a desired A/F ratio, he has a few videos on it on his RUclips channel.
Just give us the specs for the best hp combo. Wink
What is that red paint on the inside of the block called?
glyptol
I'm still learning this stuff and am wondering if this would have the same effect on my combo? I have a similar 383 short block, but only have forged pistons. I'm currently using a flat tappet cam with 234/234@ .050 and .480 lift and 114lsa. I've been planning to upgrade to a retro roller but am unsure whether I'd see such a dramatic escalation in HP and torque numbers.
You should check out David Vizard. According to him, your cam is way wrong. He has plenty of dyno results to prove his choices of parts.
there are much better cams for your combo
Hey wait a minute I was told a regular small block Chevy small block 600 max are you telling me you got 700 hp out of a regular Chevy 010 casting block ?
we've done lots more
@@richardholdener1727 so please help me out here I’m thinking about getting a dart block but if I can save some money and get 7+ horsepower out of my small block 350 four bolt main 69 block maybe early 70s 010 Casting If that’s possible what do I have to do
Richard, is it possible to have a carburetor that's too big for a motor?
Yes it is you don't need Richard too tell you that
yes
@@richardholdener1727 I thought a carburetor squirts fuel in based on the amount of air it is sucking in so based on that I thought it could not be too big but what would the symptoms be if it's too big?
you kept the compression at 10-1 with the supercharger???
yes
what was the compressıon ratıo before and after the cam swap?
cams don't change static compression
@@richardholdener1727 Hi Richard.. I have sbc383 gen1, with 144 B&M Blower. 8.5 comp. ratio. Can I run 10psi with pump gas? With this cam. Thank you..:)
Here's an odd one, I'd love to see a comparison of two setups with equal lift at the valves but different lobe lift and rocker ratio.
For example .575" valve lift with a 1.5 rocker and a .383" lobe cam vs 1.6 rocker and .359" lobe cam. Does it do anything measurable? Is there a larger rocker ratio to push the example farther like a 1.65 or 1.7?
I like the way you are thinking!
I just installed a set of 1.7 ratio scorpion roller rockers on my 92 c1500. Regular old 350 motor with 267k miles. It added 13% more valve lift with essentially the same duration.
You can find different ratio rockers. 1.5 and 1.6 are most common, but you can find higher ratios for racing or lower ratios for easier flat tappet cam break-in. I think I've seen 1.2 ratio for break in. I don't know if they make 1.8 for sbc. I'm sure if your pockets are deep enough, someone will make a set. Lol.
The 1.7s were about double the price that I paid for my 1.5/1.6 roller rockers.
@@EricErnst I've got Comp Ultra Pro Magnum 1.52 in my supercharged small block combo. I'm curious to see if there's a measurable difference in performance when using a small cam and larger ratio rocker vs a large cam and small ratio rocker. There's plenty of examples of just changing rocker ratio but that's not my question.
@@EricErnst Any lift will help the stocker cam out. A stock LT-1 cam from a Y/F body is a huge improvement on that engine too or the Elgin 210/215. Then again, you don't have to crack the engine open to do the rockers etiher.
@@thetriode I've got an extra xfi252hr cam lying around. It's 252⁰/264⁰ advertised, 202⁰/212⁰@.050". 114⁰lsa. .550"/.546" lift with 1.6s. Very short duration for great off-idle torque. The tbi heads flow terrible and the stock tbi can barely keep up with a stock 350. If I used a bigger cam, the heads would run out of air as the cam is coming to life.. and the big cam would kill low end torque. I'm going to bump up fuel pressure on stock injectors and try to get 315hp worth of fuel out of the pair of stock injectors. 315hp out of a 350 is pathetic, but with stock tbi, I think it will be a fun project. The stock cam in those trucks was something like 165⁰/175⁰@.050" with .385"/.402" lift. No wonder they only rated the motors at 190hp!
I mean I guess the stock truck ones were rated at 195hp so like 400hp is probably not that hard for a 350
if you had the wrongest cam possible to start with.
Well ok, yes, the application is supercharged.
I think he added 200 hp from cam heads and boost. Not just cam
You made this sound like just changing a stock cam is going to increase engine by 200hp. Said nothing in intro or header about the engine already being blown. Thought somewhere you were going to get to the NA gains. Thats why I watched the whole video is because sometimes you have different tests throughout the video. Was waiting for the one described in the header and beginning of the video. 200hp gain with a cam swap on a blown engine is not a big deal.
watch the 175-hp na ls cam swap-that should make you happier-but you missed the point of the test
Wow that’s crazy how much it lost
I'd push that motor to 7000rpm with some bigger heads and a single plane with a 900cfm Dominator.
Is this Vortec supercharger a procharger?
it says right in Vortech in the video
What did the boost curve and PSI look like after the cam swap? Did it bump the boost up with the diminished flow of the small cam?
boost was higher with the stock cam
Better quit fighting with your brother over cams..😁
Well yup, turns out to be clickbait right off the rip! 200hp cam swap,,,WITH BOOST! People be clicking seeing 200hp cam swap thinking naturally aspirated! But yes, car guys are going to more than likely still watch it.
I got 175 hp from an na combination doing the same thing on an LS-200 hp is possible with an NA combo-but obviously you missed the point of the video
1 minute in explains it all,... little cam to a larger well designed cam and a huffer
THE HUFFER WAS RUN WITH BOTH
@@richardholdener1727 yes I seen that, I wasn't quite clear with my statement. Meant to say having a base line engine with a forced air induction system can have more opportunity for power increase because of the ample supply of air. Being the heads are your biggest obstacle at that point, anything with the valve train could be huge ! Small cam to larger (especially one designed for the application) could make obviously as you have showed drastic improvements
Ah. Now it's a "supercharged" sbc, that's already a built stroker, with a roller valvetrain......
The wrong cam can wreck ur. Day. I like to look at the cam cair. Then the cam numbers. All I know I like Lift.
ruclips.net/video/72hVhcBOyPo/видео.html Video I was talking about (and shamelessly plugging.) They make a kit to do this but you don't really need it if you have a grinder and patience. This is for a 700R4, but the TH350 governor is the same. In fact, I believe the lightest weight one is from a TH350.
Something being click bait vs having real and usable info in it are two things that aren't mutually exclusive. Someone may have stuck a ton of parts on a stock or mildly cammed engine and wonder why they weren't making any power. Such a piece of info could be extremely helpful to them. Testing in a systemic and scientific nature tells you where bottlenecks are.
thnx
So........ This kinda Blows up the never ending BS Question about the needs of the purpose of running a camshaft for boosted applications only! 🙄 The argument is that a camshaft somehow has the ability to determine atmospheric pressures and do something to improve the overall performance of its profiles for boosted and naturally aspirated conditions!?!? Really these cam profiles are different, but they're not something that is necessarily needed nor will they always improve the power output by running a "Boosted Profile" camshaft! There's lots of theories about this topic and some of these things do apply to specific boost situations.......but not all boosted situations apply. If you're running a turbocharger and take advantage of your exhausting of your engines exhaust pressures to rise, absolutely yes Sir it would be a probable benefit to run a specialized boost camshaft for turbocharger applications! The positive displacement of anything like a supercharger though....... here's where things differ. Being your compressor isn't relying on certain conditions for building boost quicker and easier than something with a positive displacement driven system, the camshaft really is not going to hurt or benefit the boosting capacity of your engine. Being you may not specifically need so much duration @ .050" to achieve the numbers you are looking for without having to deal with high stall speeds from having a big duration cam profile, you can actually get away from the chop factory and still get more air packed tighter into your cylinders. By utilizing a higher lift and a reduction in the duration for say street purposes, by making up for pulling out of the duration and building higher lift and this could easily be done with ratio rockers as well if you don't have the money to make a cam swap? Springs and a higher ratio rocker arm is going to definitely complement your boost and increase your overall output without the need for changing the camshaft profile. This is why you can actually boost almost anything you want. Will it be efficiently perfect with say a stock camshaft profile and additional lift? Probably not, but it's worth the price of doing it for the gains that you will feel and see on the dyno. Comes down to getting as much air stuffed into your cylinders as easily as possible so by increasing the lift and leaving out the needs for bigger duration, this is very possible. This is why many forced induction engines stock to street/strip, you are sometimes fooled by the sleeper effects of not hearing any lump in the camshaft department, and take the bait as it's not going to be a very fast vehicle LMAO! I made this mistake 1 time with a worked Buick GN and had a 10 sec G body 442 running a aluminum big valved heads, roller cam'ed 406 SBC with 12" slicks and got spanked by this grandma sounding grocery getter V6! It was definitely worked over, had heads cam, converter and computer work done! But you'd never know you were pulling up along side a mid 9 second car! LoL lesson learned in under 10 seconds really almost 6 seconds as I got him off the line and about halfway thinking wow thats easier than I was thinking??? SMFH! But soon as this thought passed my mind, LoL well so did his car! 👋 He was able to catch up about 2 car lengths and then surpass me at the end...... That was the last time I laughed at how weird sounding those Buick V6's sounded under load at high RPM'S! And no longer looked down at small displacement engines with a boost adder of some sorts.
start with an na power curve-then add boost
