What would be an acceptable number for the maximum amount of horsepower that can be supported on a blown motor with the stock, unported LT1 heads?

 

This would be best discussed in the Forced Induction Forum, transfering.

Thanks.

 

Ive seen upwards of over 650+rwhp on stock heads on a boosted application.

 

I smell nitrous... What was the setup?

 

396
d-1(maxed)
all the bolt-ons
JE pistons
solid roller cam
1.6rr
alky setup

Thx,

who has this setup? Any other details...must be some big dishes in those pistons for a maxed D1 and bone stock heads.

 

Why would someone spend all that money on a 396 and not touch the heads

 

I wonder if he means ported stock castings? I don't believe 650rwhp with stock, UNPORTED heads. Heck, 650rwhp is pretty decent for a D1 on an LT1 with fully ported heads.

Sorry, misquote, he was making this hp on some afr heads. He made 540rw and 520tq on some ported stock heads.

 

Ah, that's more like it!

I was wondering about totally stone stock head castings. Is port/polish work expensive, and would it be worth it to do on LT1 heads, or would LT4 or AFRs just be a better investment?

 

I am also considering going with a S/C on my stock 97 LT1 and am just wondering how safe 6lbs would be on it. I need it to last at least until next summer when I will hopefully have a new motor done. Right now I just have exhaust, headers, offroad y, airfoil, hypertech, and CAI. Thanks, Jarred
