I remember articles in the 90s magazines about the magical 500hp chevy 350........congrats on doing it on the cheap. This would have made an outstanding "king of highschool" engine build back in the day. I would love to see this engine with AFR enforcer or similar budget head.
It is absolutely awesome of you to list the exact parts you use in your builds. I am kinda iffy on buying stuff from Amazon, and it's great to have someone test the stuff it see if it's any good. Thanks a ton for being so willing to share info like this.
In did 2 work truck engines one is a 383 using 6 inch rids and the other engine is a 385 that is a 40 over 350 block I am again using the same 6 inch Eagle rods bought from Ebay which most everything now I get from Ebay because I get Hugh savings from buying off Ebay and I don't have to deal with a stupid teenager at any of the auto parts stores that 9 out of 10 trips I am getting the wrong parts and have to go back to get the clown to find the right part. By the time I finished these engines it came to the same cost as rebuilding the 350 which is far less in torque than a 383 with the 3.75 stroke crank. These are only work truck engines for pulling trailers going hunting nothing at all for racing. For the 383 I bought from ebay a pair of Aluminum heads with 202 & 160 values 65 cc combustion chambers. For the 385 the heads are GM for TBI and 65.3 cc combustion chambers with 194 - 160 values
That's actually really good power for what ya got going on there, cheap! As far as having some respectable horsepower on the street that's really cheap! With some decent aluminum heads on their you could easily make over 500hp! And if you don't know, 500hp on the street is a whole lotta fun! Even 400hp on the street is a lot of fun. Nice job on this little 355!
Man I really appreciate you sharing your knowledge. It’s so rare to find someone nowadays that really know their trade, it’s even harder to find someone willing to share that with others. Thanks again man, your videos are why I decided to go vortec in my camaro.
Excellent video as always Pat. The only thing that I think that you could do to improve it would be to quote the total Canadian price at the end of the video. Then I can make sure that I’m sitting down to hear the bad news.
The Summit cams are a lot cheaper than the name brand ones. Last time I bought a Summit cam KIT (with lifters) it cost $79! Yeah it’s been a while. The Summit flat tappet cams are roughly half the price of a Comp.
Look like the old proform cheapies. Leraned my lesson the hard way on "budget" valvetrain stuf. No way...save and get some good ones. Used on a hft baby sbc cam (isky 280) if they cant handle minimal seat presure for 200 miles then...ticking time bomb . Some roll the dice and claim victory but my $ doesnt come easy
When you mentioned the cam break in with 1.5 rockers I wondered if there was an even lower ratio for the SBC and sure enough they make a 1.3 "break in rocker". I'll be getting a set of those for my next flat tappet cam install. 🔧
Excellent content. Thanks for the rundown. I would love to see some experience with the Skip White NKB's; their sales pitch is compelling; it would be great to have some objective observations.
@@cuttersperformance If I remember right, it's the same casting as the Amazon heads you flowed, the "AFR Enforcer"/DNA/ProHeader Chinese casting with 11/32" valve guides. Is that what you're seeing when you look at them, Pat? Hope they're different, more data on the options out there is always awesome.
Thank you Pat! I truly like it that you keep pushing these old small block chevy's, while many are so much into LS. I'd love to see you make a build using the Chevy's aluminum 113 castings! Would this be possible? Btw, who's playing the guitar in the video?
Thanks man, appreciate that. It would be hard to get a set of 113s to this level but would be interesting to try. The guitar is just royalty free music off the mac software
@@cuttersperformance Those, if you can find them suck dont waste your time . You have to put a TON of time and $ (seats larger valves) to get them to do anything.
building a s10 currently going to go with this for a baseline for the 350 which i got junkyard heads for 50 bucks on a all you can carry day so im going for budget build
Can you speak to the quality of summit brand sbc crankshafts and rods? Where I live it’s cheaper to buy new rods than to get the stock ones resized. Thanks for the great information!
Hell yea NICE IAM wanting to build something very similar for my sbc ,i have a set of patriot freedom heads aluminum, got them super cheap i heard they are like the vortec heads but better ,wanting to port them , then pick cam says they can hold up to 600 lift lol not sure
Definitely do a dyno test with out of the box nkb heads or Dart 200cc pro-1 or other Dart copy head as a comparison. But I can already tell you the over priced AFR enforcers will make the most power out of those.
To everyone in the comments notice he is NOT using flat top pistons. This engine in this video is using a mild / small pop up 11:1 pistons and its for good reason. Compression is our friend when it comes to HP well to an extent. Application specific street or race basically how do you plan on using your engine rpm wise ?
Cool video. Would be awesome if you’d show the dyno graph. Would love to see the torque curve. I recently came across your videos and enjoy watching them. Thanks!
Really concerned with my current build, it was in a 62 C10 I bought 'just rebuilt" wiped a couple cam lobes. Machine shop did the eye roll when I said I'd still run a flat tappet cam because they jacked the heads up so bad with a poor threaded stud job and that caused the issue, one actually fell out of the head from not being tapped enough. Several others were close. I have Brodix heads for it now...just not locked in on the flat tappet now and considering retro roller..
That’s awesome a build 👍🏼 I’m gonna pass on the flat tappet camshaft though. They are hit and miss nowadays and for piece of mind I’m gonna stay with OE roller step nose. 108 overlap with a 248@50 is little too big for me in a street car but I bet she chops 😂
@@cuttersperformance aren’t you a machinist by trade? How much for a set of vortec reworked with decent springs out the door? With trade in or without a core ?
great video, how about trying flat top piston basic cleaned up vortecs and a LT1 cam and a air gap , only because thats the spare parts i have layin around
You dont really worry about the initial on the dyno as it's basically at full advance when the pull starts. If I were to set this up on the streets. I probably start around 20 ish initial with 5 to 10 deg of vac advance and 35 total. I will have to check my notes on cranking compression, but I believe it was around 185
I did a 383 for the first time then the machine shop that did the work told me my 383 did 480 hp and all I wanted was a work truck towing engine, so I just bought parts not for race for a work truck engine. So, making horsepower from these 383 must be pretty easy
Great build, do you think that intake manifold would fit under a stock hood? I have an 81 Gbody. I guess we can also wait to see if it fits in your buddy's Grand Prix!
Great video question on your heads are they 64cc and plus on that summit cam#1205 you didn’t run into any problems with valve to piston clearance issues because of the lift 510 int/518 ext. just curious cause I hv a LT1 style sbc in my 74 Corvette right now.
No tire would be safe! As I sit here with a shit eating grin thinking of the sweet, frothy burnouts I would do if I had this on my s-10. 😎. Killer little mouse👍

Instant failure waiting to happen!! Just, NO WAY!!! I've got a set of Isky HY202 lifters, and they are much better, although I'm not totally impressed with those either!

Check out Trend performance that makes some excellent valve train components that a lot of top fuel engine builders use as well as the outlaw sprint car engine builders . They make custom push rods & cam shafts and were the first to build & use what's called the spin tron to watch the valve train at high rpm in slow motion to see what the valve springs & valves as well as push rods were doing to design and make better valve train parts . They also sell cam shafts and lifters for the more common older V8 engines so look into them if your looking for really good valve train parts . Also look into Elgin stainless steel full Roller rockers for SBC because they are built very well for the money compared to even the comp cams stuff now for less money .
How did the valve covers clear those rocker arms? I got the KMJ Assault rocker arms to go on a set of vortec heads. I picked up the aluminum tall centerbolt valve covers. Did you have any issues with clearance? Also make sure you inspect the arms as i found one without a fully machined Clip grove so the clip would have worked its way out into the head then the pin could have worked its way out. They sent me a replacement rocker.
@@cuttersperformance Had a set of look alike Proforms that puked in no time flat...Isky 280 mega cam DIdnt even get 300 miles out of em. Small fulcrum crap quality. Myfault for thinking cheap would be ok at the time Crower or JEsel these days will wait and save. lol
All of you 'porters' keep in mind that blowing through all you need to do is be too thin, you do not actually need to see the other side. Coolant shall transfer to the other side through iron because it is hot and condenses straight through it as if a hole were there.
cool thanks for the response, just for anyone starting out you know reading this stuff. Thanks a ton You help us all and make this fun.@@cuttersperformance
Stock l31 block and heads…. I’m searching for a cam for my father son project and wanted to run a new piston to hump the compression up…. Curious if those pistons would be an issue on a lower lift cam under .510 lift).
That 1205 cam went up 23%... the $130 price [at 2:14] can't be from one month ago? Or are core shortages that big a problem? Are we really entering a 276% [annuitized] rate of inflation?
Those are the same pistons I was thinking about using to get the higher static compression. IIRC it's the 1970 LT1 350 replacement pistons. What was your thought process on using the 240 grit instead of the 320?
@@cuttersperformance I just honed a .060" over 350 with the same hone because I was cheap (first short block I'm building). The 320 grit was $30 more. It's not a must but I wish that piston came with the thinner ring pack for the same price. You'd get 8-10 more hp with it.
I did! Yes... with same spring kit and ebay aluminum heads. But I bought .100 longer valves to compensate so I would not have to cut the spring seats (so I could get adequate installed spring height)
?? Really good info ,thanks,,,,??what type of rear end do u use in that 3rd gen firebird? Do they hold up to most of your 480 hp budget builds with that torque?
Hey Cutters, quick question. Do you remember the exact piston to head clearances? Im running pretty much the same build but with a 15 thou taller piston than yours. Thanks alot !
i have the same springs from summit but mine are 490 max lift. haven't cut the guides down or anything. recently put a Howards 480/488 cam in the truck. I'm wondering if the 490 max springs are enough? I don't want to deal with valve float issues. what springs would you recommend ? thanks
You must have the sum-174001 which around around 105lbs on the seat and good for .490 lift. This is on a vortec head? Did you check retainer to seal clearance?
@@cuttersperformance yes there vortec heads. when i built the engine for my truck i didn't know to check for retainer to seal clearance sense it was my first time for everything. but watching some of your videos I'm nervous about running the springs in it now. haven't seen anyone run my type of springs with a cam like mine on the same head . And now I'm not even sure there strong enough since everyone runs stronger springs with cams similar to mine
@ethism_14w21 has the engine ran yet? If not, dont start it until you check the retainer to seal clearance. Id be more worried about that than floating the valve with those springs. Im assuming its a flat tappet?
@@cuttersperformance yes flat tappet. It’s hard to tell the exact amount of clearance I have valve to seal with the inner spring inside of it. But by looking at some of the valves that’s are all the way open and spring all the way compressed with this cam it looks like there’s enough room. More than .50 thousands
this is amazing. I'm building almost the same engine except iM building for a cruise in a 63 impala, 207 block 4.03 same pistons 9.5 compression. i have a windage tray from speedmaster, stock melling oil pump, my heads are ported 993's. i'm using these heads because they belonged to my brother who passed away. stock 64-65 350hp 327 intake looks alot like rpm intake and a eddie vrs 650 and pentronix 3 dist cam summit 214 224 ,444 465

What carburetor was used for the dyno run?

@@cuttersperformance Thanks.
Do you have a recommendation for a hydraulic cam that may make similar HP/TQ with more vacuum? Thx
Dingle ball 2.0 video is coming up. It has slightly more vaccum than this combo
man i need to buy something to throw that engine into, like that 4spd 2nd gen i sent you lol
Yeah that would be perfect
Hi Pat, Do you think I could use that Summit spring kit on a set of DNA heads, as long as i use a spring locater.
Yeah you could, might just have to use a different valve seal
@@cuttersperformance Thanks Pat, and thanks for all the great videos.
I did! Yes... with same spring kit and ebay aluminum heads. But I bought .100 longer valves to compensate so I would not have to cut the spring seats (so I could get adequate installed spring height)
@@hotrodswoodshed7405 Thanks for the info.
?? Really good info ,thanks,,,,??what type of rear end do u use in that 3rd gen firebird? Do they hold up to most of your 480 hp budget builds with that torque?
I'm running a borg warner 9 bolt. Was running a supercharged 383 ran mid to low 11s. Now the car is going turbo
What's your opinion on 441 heads vs vortec with 11:1 pistons on 93-94 octane? Do-able?
Hey Cutters, quick question. Do you remember the exact piston to head clearances? Im running pretty much the same build but with a 15 thou taller piston than yours. Thanks alot !
Hi what's the part number on the exhaust valve and vendor . Thank you
Curious how this cam would run in my flat top 383sbc with sportsman 2 heads?
I actually designed that cam for a 383. I'm have another one on the way to use in an upcoming 383 build. It should work quite well
i have the same springs from summit but mine are 490 max lift. haven't cut the guides down or anything. recently put a Howards 480/488 cam in the truck. I'm wondering if the 490 max springs are enough? I don't want to deal with valve float issues. what springs would you recommend ? thanks
You must have the sum-174001 which around around 105lbs on the seat and good for .490 lift. This is on a vortec head? Did you check retainer to seal clearance?
@@cuttersperformance yes there vortec heads. when i built the engine for my truck i didn't know to check for retainer to seal clearance sense it was my first time for everything. but watching some of your videos I'm nervous about running the springs in it now. haven't seen anyone run my type of springs with a cam like mine on the same head . And now I'm not even sure there strong enough since everyone runs stronger springs with cams similar to mine
@ethism_14w21 has the engine ran yet? If not, dont start it until you check the retainer to seal clearance. Id be more worried about that than floating the valve with those springs. Im assuming its a flat tappet?
This video should be able to help you determine what clearance you have. ruclips.net/video/tNVX3W-KHT0/видео.html
@@cuttersperformance yes flat tappet. It’s hard to tell the exact amount of clearance I have valve to seal with the inner spring inside of it. But by looking at some of the valves that’s are all the way open and spring all the way compressed with this cam it looks like there’s enough room. More than .50 thousands
A change too a solid lifter cam should pickup some torque and maybe a bit more power no other changes
What lifter pt# do you recommend for factory roller?
Summit Part# HT217-16
If you ran an electric waterpump on the dyno do you think it would have cracked 500hp?
They are worth 4 to 7 HP
do you know the seat and open cam spring pressure?
I'm considering a twin turbo 355 vortec head set up any recommendations
If you did sell it, what would the price be?
Not sure what Id let it go for
Pat- do you build & sell engines? If so, do you have a website? I looked and didn't see one?
Yes I do, but I don't have a website yet. I'm currently about a year booked up for builds.

Is a 4 bolt main absolutely necessary? What was wrong with a 2 bolt?
I want to use the vortec head on my small block 400 can I do that and drill the steam holes
Yeah you can, i actually have a 406 vortec build coming up
@@cuttersperformance
Ooh nice. Waiting for that one.
If i dont wanna go the route of carb what intake should i hold with
do you know what kind of difference the 1.6 rockers make over the 1.5 rockers on this engine?
unfortunately, I did not try 1.5 rockers on this engine
260cfm @.550 is a strong number. Great job man👍🏻
Are the pushrods stock length?
Could this build handle a twin turbo kit?
Would this build work for a daily or is it too much ?
how much did it cost to build? i would love to buy this motor!?!!!
this is amazing. I'm building almost the same engine except iM building for a cruise in a 63 impala, 207 block 4.03 same pistons 9.5 compression. i have a windage tray from speedmaster, stock melling oil pump, my heads are ported 993's. i'm using these heads because they belonged to my brother who passed away. stock 64-65 350hp 327 intake looks alot like rpm intake and a eddie vrs 650 and pentronix 3 dist cam summit 214 224 ,444 465
