Taking Bets!

[500/600]

Well bro, at least you got your car to the dyno. Most folks just talk s##t about doing it their whole lives and never do. Hence all of the 500hp SBCs.

For what it's worth, you should consider a 430 or 455 before you sink money into those aluminum 350 heads only to see maybe 300rwhp. Put another grand in a rebuild kit and some home port work into a good used 430 or 455 and you'd likely be closer to 400rwhp...……………………..and still be rocking a Buick.👍

It's not going to be cheap, it wont make as much power, but I really like the SBB. If power is what I was after, I'd have done an LS swap back in 2014 when the v6 blew up. If it was just big buick power I was after, I probably would have done a 455 by now. But, I like the 350. It's a neat little engine. And when I do get the heads, it's going on an engine a LOT better than this one. Goal for that is 400rwhp. TA built one as a test mule, 10.5:1, headers, dual plane intake, 750 holley, .650 roller, etc. 481 crank hp with mild head porting of the ALs. Say nothing of potentially doing my version of a GN, a turbo'd 355 that would be lighter and torquier than a similarly built all aluminum LS engine. But that's for another time.

Unfortunately a lot of people view they dyno as a way to earn bragging rights by having a piece of paper, and they have no interest in using it as it was designed. I like to call it the dream crusher because everyone thinks their 9:1 350 with fuelie heads makes 500 hp

Some of us with a advertised 300 horse 10:25 compression 350's would be happy if I got 250 horses out of it.

 

[Max Headroom]

No. What I'm saying is the open chamber design of the heads means that there is no conventional quench zone. at all. so the cylinder walls and piston top acts as it's own quench pad, if you could call it that.

OK. Got it. Thanks

AMEN!!! The most important thing is build the engine YOU LIKE!!! I got grief for building a 409 " you build (insert anything) for less and make more power)" they said . NO I WANT A 409!.
Build the 350 and make it the best 350. besides I am sick of hearing about LS.

Didn't rain here last night. If you really don't like living in Iowa? You should move now. It will only get harder the longer you wait. My brother lives in Montana. He has lived all over the world and said Montana is the coolest place he has ever lived. My thoughts on your dyno deal. Who cares how much power you actually made according to that. Use it as a way to compare and improve on. You have a car not too many people have that you built your self with an oddball engine. It takes big money to make big horsepower that does not work very good on the street. I am happy for you.

I’m thinking of a Thermoquad.

No, it takes 30 seconds. I am surprised he doesn't have them set loose with a 2500 stall and 3.42 gears. Crazy on the quench, Dodge ran nearly as insane quench, pistons .080" in hole on the 318, even the later Magnum version is .040" in the hole. Buick 350 heads have terrible flow on the exhaust side and intake isn't any hell either. Still a torquey, light weight design, something different.

I got some tuning to do then.

Be careful, your on the fat side now
