Building A Brand New 434 SBC!!! How Much Power Will It Make? 

Thank you hoping to be racing here soon!

Thank you, hoping for some low 6 sec passes in the eighth of a mile

Thank you!

Thank you… I appreciate the support!

Yeah can’t wait to get it in the car!

About 10.5 to 1 Compression. I run a 1250 Dominator. Solid roller cam and we turn about 7500 rpms!

Yes your right about the milling, i said the wrong word when working. But the setting it at .025 cold the metal swells when it gets warmer so actually tightens the valve train

That's actually backwards you set cold lash tighter with your iron block and aluminum heads it will actually grow .006 when it's up to Temp. I do this to all of my dark small block with aluminum heads my cam calls for .020 hot so I set them at. 014 cold.. 770 lift solid roller

Ya your right!

It’s small based the block also is machined out in some places for the rod clearance

How’s it going

I ordered that from Summit about 6-7 years ago

I meant to say Milling up the compression

It’s an Erson Camshaft

Cam specs?

Not very much especially since we run 116, I don’t even know if i could give you a rough estimate

measured in smiles per mile :)

@@JimBronson Yes Sir!

Based on the 116 reply... the hole in your wallet is somewhere inbetween Steve Howe and Billy Idol sized on an average 80's weekend.

I don’t quite understand what your asking.

@@mr.luckyracing7112 I’m asking about the lobe separation on that camshaft and also about what rocker arm ratio you’re running

@@kristjanstefansson2765 It’s a 0.475 Lobe intake, a 0.45 Lobe Exhaust. And the rocker arm ratio is 1.5

@@kristjanstefansson2765 If the LSA is not down 106 area he is leaving power on the table in my opinion

At that lift with 1.5 it’s def close to that. Runs real nice too. Nice build. Can you share duration at 50?

I believe all the parts came out to about $15-16k

Hell Yeah🤟

Yeah, I believe out of this motor we are making close to 800 hp

​@@mr.luckyracing7112 hard to guess without more info but I'd guess 629-694hp na all motor (really wide range but without knowing more about the cam, no porting, 10.5:1...) Looks fun

@@mr.luckyracing7112 you absolutely are not making 800hp out of that

@@1000machz We had our old motor which was built the exact same just without milling the heads dinoed. Made 785 so just shy of 800.

@@1000machz ummm lmao have you been living under a rock? These 434’s can make upwards of 800 easy with 14.5 compression at 8rpm… shafiroff makes a engine that even makes a sb.2 434 making over 900 and yes it’s natural aspirated..

That’s gonna be a hell of a motor

What headers are u using size

@@mr.luckyracing7112 thank u

Chad knows his shit

@@stevenbelue5496 I hope so I got alot of money in these heads

Yes it is… It is a 4.125 bored Sbc dart block

Lmao what? Are you dumb or just trolling?

untrue

It is an Ohio Crankshaft bottom end so all the specs about that our on their website. It’s a billet oil pump, It’s a Jessel Sbc belt drive kit. And am Erson Camshaft Speced for the heads we run.

He doesn't fully understand a lot of what he's talking about.... like uping the compression with porting the runners of the cylinder head lol and the reason for having to run offset rockers due to port location, valve size, head casting design or pushrod size, not to make it easy to adjust lash. He's a kid learning...

They do help the rocker arms last longer by putting the load across all of them and not putting stress on each individual rocker.

He mighta porting, up the compression. as in ratio.

Not porting it’s called milling the head brings the compression ratio up a little

@@mr.luckyracing7112 NO shit I was referring to what the kid said lol

@@danstomber1664 We just used the wrong term in the video… I was just correcting it not trying to be a smart ass.

@@mr.luckyracing7112 Me either sunshine

The unofficial definition of disco: perverts hooked up with drug addicts, and disco was born! But seriously... at least music was chosen [no I didn't miss the Floyd or Clash in background moments]. We could have been subjected to (c)rap - and we wouldn't have watched to the end of this magic, mathless, wrench-a-thon with nice shiny bits. Did you catch compression or cam details? I freakin missed it. I think it will turn out ok: if I had to roll the dice in bolting on heads without disassembly and inspection [and some light blending] AFR is the best candidate. So here's my dartboard guess (to stay on topic).......546hp [na]. And of course, that will be wrong.

Why do you say that?
