I really appreciate that you spend time with both oddball engines and popular ones. True gearheads have a wide bandwidth of interest and are not brand loyal boo birds. I love all kinds of different engines from model T Fords to Hondas, and LS's , too!! All of these things are really fun to play with and learn about. The rec port 6.0 LS in my 53 year old Land Rover just went "Clunk", now I'm learning about how I can build a stroker out of what's left HaHa!!
Majestic. Rewatched at least 5 times. Next we need to see 250 + intake cam. 12.5 compression. And test ethanol vs methanol. 600 hp would be magnificent
540 hp out of a 327 CID NA engine that lasts. Great time to be a hot rodder. This would be a fun engine in a street car with a manual transmission and aggressive exhaust sound, let it sing.
Been watching your vids for a while now and you never disappoint... im building a gen 3 6.0 for my camaro and your vids have really helped me with what path i wanna go with her! Ty for the vids keep up the great work!
@richardholdener1727 i didnt think these heads would work with a 5.3. I have been looking for something better than the 706's on my rcsb silverado. Its a street strip truck. 4l80e swapped 4k ptc converter, 4.56 gears, tru trac posi, 1 7/8 LT headers, btr stage 3 truck cam but swapping it to a btr red hot cam and using nitrous outlet x series single fogger nozzle for no more than a 200 shot. My lm7 5.3 is stock bore space 3.780 with dish pistons. Would you say that these 220 fast as cast heads with .030 milled off and a .041 mls gasket and the btr redhot cam work great together?
I'd like to see a David Vizard spec'd cam for this combination. He seems to be a fairly sharp ole fella , I'd like to see his theory in action in a back to back test. Thanks for all you do Richard, keep up great work. It is truly valuable.
BT would be offended if DV’s specs made more avg power. BTR throws Rich a lot of bones! BT & DV have opposing views on cam specs, specifically LSA’s. DV says they are key and BT says they mean nothing! The videos are out there saying so....
M1 of course!!! It will push some nice numbers and give it a good cleaning! Lol. Just remember to run some regular through it afterwards and toss the oil.
So on 6.0, with similar mods, we could see 600hp, maybe even more with rec port heads? I would love to see this same setup on a 6.0, reving to the moon. As always love the videos, great info and nothing beats the sound of a screaming LS.
I really like your testing, you have the best LS information on RUclips. How about testing exhaust, header diameter and exhaust diameter. example 1-7/8 header with 2-1/2 exhaust vs 1-3/4 headers with 2-1/2 exhaust. you could also include 3" exhaust. this would be really helpful for us daily driven guys.
All the old sbc guys were happy with 1 hp per ci. Taking stock junkyard stuff now days and getting 100 hp per liter is no joke. My 6.0 is making about that n/a and it’s a wild ride For stock junk.
I would like to see an overlay with the previous configuration. Also I would like to see some testing with Texas speed CNC ported 243/799 heads. I want to build and swap a 6.0 into my 1973 Nova, but the numbers you are getting with a more readily available 5.3 has me reconsidering that idea.
This setup with a 6-speed MT and Nitrous to makeup for torque loss in a foxbody would be badass. Let alone with a turbo.. Rich I been keeping up with your videos for YEARS and a subscriber from different accounts now lol.. can you please run a High RPM shootout with NOS + Turbo on the 4.8 , 5.3 and the LS3 Destroker to see how they differentiate or compare to one another under boost. I’ve seen other videos of 6.0s with 4.8 cranks running a 75mm-88mm turbos and they’re all sick !! Thanks Richard 🙏🏼
I was going to do a destroker, but I decided against it since I'm not keeping the car. But im keeping my 4.8 crank for my next 6.0 ls car. Want to get like ~8.5k rpm. Gonna slowly collect parts like an aluminum 6.0 block, flat top pistons, etc. Want an American version of the bmw s65 engine.
A tighter LSA does work. Richard, you proved this yourself 2 years ago with testing. The whole, it’s just a result of duration inputs is wrong. In short, Mr Vissard is correct and Mr Tooley is not. Awesome video!
Richard holdener On one of the episodes of engine masters, they were trying different size heads on I believe a 408 They showed that the 225 head was too large for that motor So if a 225 is too large for a 408, wouldn't it be too large for a 325? Wouldn't a 195 be maximum? Guys on engine masters even got great results with the 165 heads. They actually impressed themselves, brulee even said that he would take the small head and cam. Com combination for a daily driver
I'd now like to see the same combination on the 4.8 to see if you could break 500 with it. Could be interesting considering the tectalk We had a wile back.
I think we should change nothing but a trunnion upgrade, and start squeaking up the compression ratio somewhere in the 13s andE85. Bring that torque up. I do think that there is the potential that we’ve reached the max CFM of those heads. At the higher rpm range I’m wondering if we’re getting some nasty low pressure zones in the transition from the square openings to the Cathedral port. I guess what I’m saying is if we went straight to a rectangular port from a ported cathedral port, we would probably see some higher average power output.
Put the factory heads back on and see what u can do w a factory long block! I buzz 7800 with the ms3 cam and twins for awhile now. 706 heads w pushrods and springs and twin 78s. Seems fine def slowed down w less rpm at the shift.
@@richardholdener1727 so it is safe to assume that things start to stretch at that rpm, that's why you would have to worry about piston to valve clearance?
I'm curious what the overlay of the 510 hp combination would have looked like vs. this combo. And... I wonder what just changing the camshaft would have done for power and leave the LSXR on it.
More cubes would be fun. How about boring the block to 5.7 to see if it's worth it ? Run it in the exact same configuration, we know it will make more power but how much ? I do have a Gen 4 4.8 and a couple Gen 3 5.3's sitting around with a set of low mileage Gen 4 5.7 pistons sitting under my bench. Is the cost of boring, rings and gaskets worth the 40 (?) extra hp ? Inquiring minds would like to know. Thanks for the video's.
I'd be curious to see what may be hiding in a little fine tuning....just to find out how the thing is doing across the rpms....and if there is anything more there!
Great results, I'm curious about another set of injectors for nitro and single injector options for meth, water, amonia and others. What about propane injection also ? The bottom end should last under 8k for quite a while the rod/bore ratio is a screamer. I would guess you could find another 100 hp on the above suggestions, especially Nitro.
Load it up at lower RPM to see what the torque is doing and figure out what it would take to keep it alive with a 8000rpm redline. E85 and a 15-1 compression ratio.
I'm ready to see all of it !! I've got a l33 sitting around and I've been thinking about putting it in my kurtis v drive. Interested in what this little thing is capable of.
This is so badass! Man i love Chevrolets! I would love to see it stay N/A but do a high compression on M1 or different race gas with a carb on top for simplicity!🇺🇲🇺🇲🇺🇲💪💪💪
TR-1 Nice. Short runners hurt the torque a bit, would be good to see if it claws back any with the Red Hot. BTR boys like their big duration splits on their cams.
@Richard Holdener as one your tighter LSA people… you mentioned the heads were shaved but didn’t say what the new CR is? Crunching the numbers comes to a 110 LSA if the CR is at 10.5:1 but… that not gonna help peak power.
Mill the heads .090 with some thinner headgaskets. She'll thump then. Told ya the cam and intake should match🤪. The long runner intakes aren't meant for 225+ duration cams. Especially when trying to tune them on the stock ecu. Lots of guys run sbe past 8k rpm. And ofcourse good fuel test would be great.
For shits and giggles do a comparison between the doorman truck intake and the tbss intake eventhough the throttle body opening is two different sizes but still would be interesting
Awesome SBE build! Your comment about the “tight LSA crowd” really doesn’t apply here. Tighter LSA generally promotes mid-range torque (as you well know) and actually takes a bit of power away at the top end. It’s good for street and/or circle track applications where you need power over a wider range. That is not what you’re looking for in this case, plus you’d get into P-V clearance issues. I’m sure you’re at just about the limit here, though the parameters (lb-ft/cu in) say there might be room for a little improvement in the torque curve with more compression. But then it wouldn’t be an SBE. Very effective combo, thanks for showing us Richard!
I run a 212/218 truck cam to 7800 with a turbo. It would be pointless NA but with the turbo I make great low end power with the baby cam and carry it waaaaay out
nice!!. I have an LQ4 with forged rods and flat top pistons with a trucknorris cam. is it possible to see what a bone stock LQ4 can do with just a btr truck norris cam swap. im curious about what hp I making. love your vids!!
Yep, this is the recipe I'm gonna follow for a build I have going. E46 M3 party car. Here's my question - the heads you mention are hand ported. Can BTR provide similar heads for purchase or what heads would you suggest to get really close to these units? Any chance you could run this package with a carb manifold?
To get more power out of this L33, why not start with a dry sump pan and micro-finish the crankshaft. Then you could swap the connecting rods, pistons, push rods for carbon fiber ones. You could also get heads with titanium valves that flow around 500 cfm and an intake that can support them. Get the C/R as high as you can on pump gas and try to get to your next goal: 2hp per CI or 1054 hp. Good luck ;)! And maybe a custom cam with a lower LSA will do the trick. You knew it had to come from me.😱
neither one of y’all built an engine be4the5.3is 323cubic it will make623hp all day with a tsp stage5cam afr260heads injectors intake gud dyno tune efi system
So there is a real possibility for my race car L33 5.3 with forged pistons+rods, BTR LS3 NA stage 3 cam, diy 8-1 headers into 2x3" straight exhaust and diy ITB setup with injectors shooting straight to intake horns, to really make 530hp! I'm going set the limiter to 7500rpm just be on save side because I will run the car for upto 30min at the time.
@@richardholdener1727 I have matched(about +5mm diameter) the exhaust ports to the headers(1-5/8", about 42" quite equal lenght primaries about 5" collector) leaving the stock d-shape untouched. I'm going to match the cathedral ports to 3d-printed cf-nylon runners for the BMW R1200 ITBs. Injectors/fuel rails are going to be atop of air scoop/hood. Heads have BTR valve springs, trunnion bearing upgrade and cromo pushrods with Cadillac racing hydraulic lifters. Runned out budget with valves and opted for new cheap valves from Rockauto and lapped them to stock valve seats. If it seems that the heads won't flow enough after first racing season(in Finland we have 5 month summer) then I need find the money for head and valve job from a professional. Dreamed about some nice CNC heads but they cost as much everything else on this engine :)
Mr. Holdener, will you divulge the part number of the cam featured in this most exciting combination. after watching this video i would like to try this in my forged setup lm7 5.3l sbe. I, am going to hit them up for one of there cam kits with springs retainers etc.
60cc chambers, e85, and compare the trinity to the ebay/Amazon sheet metal intake. Any windage issues at that rpm? A vacuum on the pan would probably add some hp.
How does the BTR intake compare to the FAST w/short runners? Also, what about increased CR and a camshaft with a wider lobe separation? And would you have less mass and greater valvetrain stability with conical springs?
I think you should stroke it, or at least bore it over. I’d like to see that torque pick up a little down low, I think it would make it more Drive-able and less racing specific.
Please boost an LFX or any of the 3.6 DOHC "HIGH FEATURE" engines. They can make good power per pound of weight in a car. A bunch of Miata owners are swapping them in and would like to see them boosted. They are closed deck design, way better than Honda J series and Nissan VQ.
@@cedricwilson2055 depending on the gearing and application I’ve run engines 500-800 RPM past peak if it increases average power. My LS6 and LS3 currently both have a shift point 500 RPM past peak. Given this engine’s top end, it wouldn’t surprise me if the power carries well enough after peak to potentially rev over 8,300 RPM. This intake manifold and cam on an LS3 peaks at 7k and carries very well to 7,600 RPM.
I wish I could get my LMG to spin 7,000😮. It feels like it is starting to float at just over 5500, but it is just a stock PPV. My motor loves the E85 it seems to have a knock sensor issue on pump gas and giving it the Italian tune up. E85 no problems at all, floor it and let her eat. Why they didn't put the 6.0 in the PPV I will never understand, not like mileage is an issue as it is junk trying to push 6000 pounds around.
@@richardholdener1727 Hello Richard how's it going?? I agree it isn't floating the valves it has just run out of everything that a stock motor can do pushing a 6000 pound turd. It's funny that Chevy didn't put a red line on these it just goes to 6000, sort of like they knew something 🤔. I wanted to find another LMG and show the transformation of the delete and adding some cam and doing some garage head work. With the way prices are going my time might just be worth doing some mild head work to help flow. With my PPV being a daily I just can't justify going stage 3 with it and the trans will have to be built as the stock 6L80 blows from the factory. Keep up the work, there are a lot people soaking up the information on the engine side. What they are lacking is more power equals more money from the torque converter back. We both come from days of a 10 second car was a quick car, and now a Honda can run 7's?? These young men and women don't know how easy they have it to go so quick with just a little added. Hope you and the family are doing well 🍺. Thanks again, Brian

Richard! You be hyped! 😹
It would make a lot of pulls even at that rpm. Also wouldn’t a tighter lsa make more low end and lose top end?
Yep, this is the recipe I'm gonna follow for a build I have going. E46 M3 party car. Here's my question - the heads you mention are hand ported. Can BTR provide similar heads for purchase or what heads would you suggest to get really close to these units? Any chance you could run this package with a carb manifold?
talk to btr about the porting-but you likely don't need it
Rich can you do a video on the dodge,ford v-10 n/a and boooost!!!!
maybe the Ford
To get more power out of this L33, why not start with a dry sump pan and micro-finish the crankshaft. Then you could swap the connecting rods, pistons, push rods for carbon fiber ones. You could also get heads with titanium valves that flow around 500 cfm and an intake that can support them. Get the C/R as high as you can on pump gas and try to get to your next goal: 2hp per CI or 1054 hp. Good luck ;)! And maybe a custom cam with a lower LSA will do the trick. You knew it had to come from me.😱
Just start with a Steve Morris Block Mr. moneybags
Just boost it vs a 30k engine waiting to grenade lol
2hp per ci.... 323cix2 646hp... Where did you get 1054 from
@@darkshine5 You're right, I was at 200hp/ liter.
Fuckkk just looked it up 18k per rod. That's 144k in conrods alone for a V8.
Hey I want to see some gen 2 lt1 camshaft stuff 😊
Great looking piece, how much power is lost when that aluminum heat soaks?
myth
Thanks, I've always wondered that with my old 402 with the aluminum intake.@@richardholdener1727
Methanol fuel mate or Nitro let's see how much timing we can put to it.Also now you need to chase 2hp per cubic inch
Ya it's pretty hard to chase a cheetah even if you are riding one mate. 1000+ hp out of an NA 5.3L is one hell of a challenge.
2 hp per ci would be 650ish hp. Not 2hp per cc
neither one of y’all built an engine be4the5.3is 323cubic it will make623hp all day with a tsp stage5cam afr260heads injectors intake gud dyno tune efi system
Julius-you need to put dem AFR 260 rec-port heads on the 5.3L to make you some big power! lol
@@richardholdener1727 yeah lol we will just notch the bores to fit the valves.....
I would like to see it on E85 then M1 ,M5 see how that 600 ganna be easy
So there is a real possibility for my race car L33 5.3 with forged pistons+rods, BTR LS3 NA stage 3 cam, diy 8-1 headers into 2x3" straight exhaust and diy ITB setup with injectors shooting straight to intake horns, to really make 530hp! I'm going set the limiter to 7500rpm just be on save side because I will run the car for upto 30min at the time.
where are the ported & milled heads?
@@richardholdener1727 I have matched(about +5mm diameter) the exhaust ports to the headers(1-5/8", about 42" quite equal lenght primaries about 5" collector) leaving the stock d-shape untouched. I'm going to match the cathedral ports to 3d-printed cf-nylon runners for the BMW R1200 ITBs. Injectors/fuel rails are going to be atop of air scoop/hood. Heads have BTR valve springs, trunnion bearing upgrade and cromo pushrods with Cadillac racing hydraulic lifters. Runned out budget with valves and opted for new cheap valves from Rockauto and lapped them to stock valve seats. If it seems that the heads won't flow enough after first racing season(in Finland we have 5 month summer) then I need find the money for head and valve job from a professional. Dreamed about some nice CNC heads but they cost as much everything else on this engine :)
good luck
Valves & lifters. Spin it to the Moon
SAA-WEEEET 5.3 😮😊❤❤❤
Would love to see a m1 setup for comparison. E85 would be cool aswell, love the content as always! 🤘🏻
What is the rev limits of a LS / 5.3 engine? 7700 seems like a lot of rpms 🤔
Hi Richard, congratulations on the test,i was wondering how much more horsepower this exact test would make if you were to bore it 30 over?
that only adds 3-4 inches
Mr. Holdener, will you divulge the part number of the cam featured in this most exciting combination. after watching this video i would like to try this in my forged setup lm7 5.3l sbe. I, am going to hit them up for one of there cam kits with springs retainers etc.
I provided the cam specs and name (from BTR) in the vid
6:29 😂😂😂 Cars & clothes, that’s all, all my patnas know.
Change heads to less cc heads like ported 706. Other on.. Maybe show us result with fast intake.
these were milled
Id like to see this setup vs aftermarket heads. How much more power will they offer over stock ported heads.
professionally ported stock heads can make this-see the big head test video
60cc chambers, e85, and compare the trinity to the ebay/Amazon sheet metal intake. Any windage issues at that rpm? A vacuum on the pan would probably add some hp.
Stock rocker arm with trunnion upgrade???? Awesome vids as usual. Thank you
stock rocker arm-no upgrade
Wow. I’m totally shocked by this. Another myth busted by your tests. Thank you so very much!!!
I like the new swipe edits
fancy
I wana see a set of small bore mast square port heads tested on a 5.3 with a stroker crank
With it being a high mileage motor id like to see how a vacuum pump would do on it
I'd really like to see that too, and vacuum pump with big ring gaps .
me too
Lets see a 5 minute 7700 rpm hold at full song. :-) Test that cooling system out. 🙂
How does the BTR intake compare to the FAST w/short runners?
Also, what about increased CR and a camshaft with a wider lobe separation?
And would you have less mass and greater valvetrain stability with conical springs?
E85 FOR SURE!!! and why not do M1 while you're at it. Don't forget to include "the tune".
I think you should stroke it, or at least bore it over. I’d like to see that torque pick up a little down low, I think it would make it more Drive-able and less racing specific.
From this baseline, what would high performance lifters and rockers do? At what point would you expect to bend a rod or the crankshaft?
SHORT TRAVEL LIFTERS MIGHT HELP. ROCKERS NOT SO MUCH
Please boost an LFX or any of the 3.6 DOHC "HIGH FEATURE" engines. They can make good power per pound of weight in a car. A bunch of Miata owners are swapping them in and would like to see them boosted. They are closed deck design, way better than Honda J series and Nissan VQ.
Would like to see you do some testing on M5
me too
Some rumble uploads would be great!
hey Richard, can we see what higher ratio rockers make on this combination? how about 1.7 and 1.8?
NO ON AFTER MARKET ROCKERS-IT ALREADY HAS ENOUGH LIFT
I wanna see how far the power carry’s out on this engine. I bet it would go 8,500 if the valvetrain could handle it.
Looks like it was rolling over at the rpm he stopped at
@@cedricwilson2055 depending on the gearing and application I’ve run engines 500-800 RPM past peak if it increases average power. My LS6 and LS3 currently both have a shift point 500 RPM past peak.
Given this engine’s top end, it wouldn’t surprise me if the power carries well enough after peak to potentially rev over 8,300 RPM. This intake manifold and cam on an LS3 peaks at 7k and carries very well to 7,600 RPM.
I wish I could get my LMG to spin 7,000😮. It feels like it is starting to float at just over 5500, but it is just a stock PPV. My motor loves the E85 it seems to have a knock sensor issue on pump gas and giving it the Italian tune up. E85 no problems at all, floor it and let her eat. Why they didn't put the 6.0 in the PPV I will never understand, not like mileage is an issue as it is junk trying to push 6000 pounds around.
a stock 5.3l doesn't valve float at 5500 rpm, it just has the power peak there and falls off
@@richardholdener1727 Hello Richard how's it going?? I agree it isn't floating the valves it has just run out of everything that a stock motor can do pushing a 6000 pound turd. It's funny that Chevy didn't put a red line on these it just goes to 6000, sort of like they knew something 🤔. I wanted to find another LMG and show the transformation of the delete and adding some cam and doing some garage head work. With the way prices are going my time might just be worth doing some mild head work to help flow. With my PPV being a daily I just can't justify going stage 3 with it and the trans will have to be built as the stock 6L80 blows from the factory. Keep up the work, there are a lot people soaking up the information on the engine side. What they are lacking is more power equals more money from the torque converter back. We both come from days of a 10 second car was a quick car, and now a Honda can run 7's?? These young men and women don't know how easy they have it to go so quick with just a little added. Hope you and the family are doing well 🍺. Thanks again, Brian
@@richardholdener1727 from the live stream what is your burner email so I can email you so I can get you the door parts. The whole door is 68.00 plus tax so just a latch is almost nothing. I'll hook you up for all the tips you have given the community.
whats next ?? how about throwing a sloppy stage 2 cam in this package and see if you can have the most hp with the king of all cams . im sure it will lose hp but i need to know the max a ss2 will make .? my current ls a 5.7 sbe used for burnouts i run it at 11.5 afr regularly sees 7900 on the tach during a skid that lasts about 2 minutes at wide open throttle in high gear (powerglide, no rev limiter , 3.45 gears ) . elgin says cam good till 6500 rpm why is it working all the way to 7900 ? and is it still making power up there ?
your 5.7l at 7900 rpm with an SS2 is on the extreme downside of power production
@@richardholdener1727 agreed but how does it get there ? stock 241 heads with pac springs trend pushrods , in my mind it shouldnt
@@norego6237 my moms civic can do a burn out... you dont need much to spin some tires with no grip
@@sniperpronerfmods9811 well this is the internet and if its true there is a video of it , i am more than keen to watch a video of your mums car doing a burn out in top gear and killing 2 tires . cause we all know its not a real burnout unless you pulled top gear and kill 2 tires , flick us a link mate
@@norego6237 relax buddy our ls1's max is like 200hp or less at 7900 rpm
I wish we could have seen the overlay of original dyno results to new dyno results. I'm sure I can find it somewhere.
coming next
Why don’t you try the tighter LSA cam and see if it makes more power
