Thank you for all your explanations in all your videos... it is always very helpful. I especially like your machining process, and assembly mock-ups before you actually assemble the engine for clearances, tolerances, etc for your BBC 632cid engine builds.
Blueprint Engines in Nebraska sell them all the time !! John Kaase Racing built a 598 cu in 429 / 460 engine that developed 1100 Hp using the SR-71 heads as cast.
Nowhere near enough cam (or valve spring pressure) for what you call a "race" engine, and what is that cheap Import Harmonic Balancer doing on a high end build? Smeding seems like rookies at this level of build, even GM (with all their beancounters) puts a good balancer on their high end crate engines.
The cam is small and honestly if you're using an 18° head then you need to be using race gas and add compression. You can still make 1k hp with a conventional 24° head. I am. 632, brodix head hunters. Jesel rockers. Very similar build.
Nice build and good video. I'm curious though, most high end builds these days use a kickout oil pan. Why was this pan selected over something with a big kicker in it?
@@bricewiese5082 The cylinder heads on the GM 632 have a lot of upside, those will likely become the best aftermarket BBC heads once a shop like MBE gets ahold of them and fully realizes their potential. Also, GM never tunes their crate engines "on kill", there is a lot left in their 632 with just fuel, and tuning.
Well have a gander @ 12:58 , the oil pressure is 20psi at 1000rpm idle... not sure why, but that doesnt sit well with me with an engine of this calibur.

Good job dude, love the sound of a big block chevy!!

Not all dynos are the same they can very plus or minus 100 hp.
That’s a nice piece. I chuckled when I noticed the Greta addition. Tribute to Steve Morris? 😏
I like how you torque the shaft rocker adjusting nut's lol😃
You have to do extreme improvements to keep that thing cool it's a BBC baby
I'd like to borrow that Sucker some weekend for a few pokin around passes on the peddle.
Greta Thunberg sticker! 😂🤣🤣🤣🤣😂😂 Cool man! Does it says "How dare you"?
Camshaft holding it back.. but it's still a beast
Love the photo of the angry Swedish truant staring back at you 😂

What's worse than that is he didn't clean off any casting flash.
I wonder how much a cowl hood friendly front inlet EFI manifold would effect power.
I love the 632 ive got 1050 hp in my ute.
With that much stroke! It should have a way better pan, & definitely a vacuum pump!
In some cases a vacuum pump made 20-40 more hp.
Is that next week 427 build your next engine?? 🤣🤣
Love the builds keep ‘em coming
1000+ in NA sweet no power adders here folks
Nice bracket 632 probably pick up 50 hp with a vacuum pump.
What kind of heads are you using
The heads have to be holding that motor back
Something is holding it back. Cam seems small too. Should have just bought a LS with a blower. Hope its a Super Gas dragster or something.

That engine did not sound happy on the last couple pulls.
I'd like to see the lash when it's cold?
Nice
It looks like you have an oil control problem after 6400 rpm looks like down to 40,s to 50,s maybe oilpan.
Nice build and good video. I'm curious though, most high end builds these days use a kickout oil pan. Why was this pan selected over something with a big kicker in it?
I noticed that too. Even with my mild 600HP small block, I run a good pan to prevent windage and add a few HP.
You need to get your hands on the gm 632 and put it on your dyno. The gm heads can't be doing 1000 hp on pump gas can they?
The GM 632 makes 1000 HP on pump gas, and turns 6900 rpm, remember the GM engine does it with a Hydraulic Roller cam too
@@donavan2676 yeah it's pretty crazy

💯%
@@donavan2676a lot left in the zz632? Do you have any evidence to support that or are you comparing it just to their previous motors?
Prediction. Torque. Plenty of it ; )
Lol nicely done. Didnt disappoint ; )
Hate the chrome valve covers- 1984 called and they want you to stop using them…otherwise nice job!
What are cam specs. ?
148👍's up thank you for sharing
How much air does that TB move? Wondering if its enough
Not enough for me, I already know that from trying it out on my 598
1440 cfm.
pump gas?
I wouldn't trust anyone to build engines who was to lazy or ignorant to pronounce Chevrolet properly.
Kinda weak
just buy a gm crate motor
Why is it dropping oil pressure by over 20 pounds As it's About five thousand r p m up oil pressure is dropping fast
I noticed that too. At around 6500 it has 40 psi.
@@tinafucinari9238 That is crank windage. They have a cheap oil pan and that is the result. I'd never run that pan with a large stroke engine.
