Dyno Testing & Tuning Smeding 1,000hp 632" Big Block Chevy!

[@DuneWest]

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.

[@alvinnelson4439]

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

[@ronsmith7739]

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.

[@jims2286]

Not all dynos are the same they can very plus or minus 100 hp.

[@woods-garage]

That’s a nice piece. I chuckled when I noticed the Greta addition. Tribute to Steve Morris? 😏

[@briancassidy1102]

I like how you torque the shaft rocker adjusting nut's lol😃

[@Hammerback0]

1:33 hilarious edit.

[@censorshipiscommunistic]

I'd like to borrow that Sucker some weekend for a few pokin around passes on the peddle.

[@forsterbargerjr2246]

What kind of heads are you using

[@PAUL_K]

Greta Thunberg sticker! 😂🤣🤣🤣🤣😂😂 Cool man! Does it says "How dare you"?

[@Sir.VicsMasher]

I wonder how much a cowl hood friendly front inlet EFI manifold would effect power.

[@brianholcomb6499]

With that much stroke! It should have a way better pan, & definitely a vacuum pump!

[@merit2584]

In some cases a vacuum pump made 20-40 more hp.

[@David-xh2yt]

Love the photo of the angry Swedish truant staring back at you 😂

[@Rome3aaro]

Camshaft holding it back.. but it's still a beast

[@drcolster]

Good power.... I'm just thinking that Oil pans too small... 75 oil pressure, 6 to 7 seconds later 50 psi...

[@darringrey4329]

I'd like to see the lash when it's cold?

[@Wormser_mcfrazzleweiner]

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?

[@toomanymodz]

I noticed that too. Even with my mild 600HP small block, I run a good pan to prevent windage and add a few HP.

[@golfr600]

I love the 632 ive got 1050 hp in my ute.

[@donavan2676]

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.

[@Sinister_Reaper]

What's worse than that is he didn't clean off any casting flash.

[@bricewiese5082]

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?

[@donavan2676]

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

[@bricewiese5082]

@@donavan2676 yeah it's pretty crazy

[@donavan2676]

@@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.

[@darrylgibbs7553]

💯%

[@merit2584]

​@@donavan2676a lot left in the zz632? Do you have any evidence to support that or are you comparing it just to their previous motors?

[@fulltiltboogie5321]

Is that next week 427 build your next engine?? 🤣🤣 Love the builds keep ‘em coming

[@mikedownen3962]

You have to do extreme improvements to keep that thing cool it's a BBC baby

[@geraldwhipple5389]

Nice bracket 632 probably pick up 50 hp with a vacuum pump.

[@ss1969steve]

Nice

[@justinw6448]

How much air does that TB move? Wondering if its enough

[@JR-The_Godfather_of_Horsepower]

Not enough for me, I already know that from trying it out on my 598

[@merit2584]

1440 cfm.

[@LOSTINTOUCH30]

pump gas?

[@michaelparadisis4076]

What are cam specs. ?

[@jims2286]

It looks like you have an oil control problem after 6400 rpm looks like down to 40,s to 50,s maybe oilpan.

[@davidreed6070]

The heads have to be holding that motor back

[@taylorsrus9543]

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.

[@davidreed6070]

@@donavan2676 I haven't seen the other videos

[@merit2584]

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.

[@stevewix]

That engine did not sound happy on the last couple pulls.

[@richardrichard4394]

1000+ in NA sweet no power adders here folks

[@rikiwakwak]

Prediction. Torque. Plenty of it ; )

[@rikiwakwak]

Lol nicely done. Didnt disappoint ; )

[@scotthultin7769]

[@edwardthekingofthestreets]

Hate the chrome valve covers- 1984 called and they want you to stop using them…otherwise nice job!

[@michaelangelo8001]

I wouldn't trust anyone to build engines who was to lazy or ignorant to pronounce Chevrolet properly.

[@123pap]

Kinda weak

[@peejay448]

just buy a gm crate motor
