Re: What would it take to build a 600hp NA, SB?

i had my 350 stroked to 383 w/ forged rods and crank. fully ported and polished camel hump heads, valve replaced with ss 202, 196 exh. barely pushing 500hp with pump gas. to get the other hundred maybe a blower or turbos. I am interested on what everyone else has to say since I would love more horsepower. (my heads and block are 1968 non#'s but correct year)

Are you saying you have a 2.02" intake valve and a 1.96" exhaust valve in a SBC head?

Yes and no, They are 2.02 intake and 1.60 exh. 1968 corvette camel hump heads (factory 300hp fuelie heads) the heads had to be machined and per machinist cut for larger valves

Re: What would it take to build a 600hp NA, SB?

if your looking to build 600 hp n/a fuelie heads are one of the last parts ID consider useing, the current 18 degree heads would be far more likely to get you to 600hp, but you might find this interesting, but read closely your not just going to slap those heads on a nearly stock 350 shortblock add a cam and go race!

Re: What would it take to build a 600hp NA, SB?

It would be easier and more reliable to supercharge or put a turbo on to hit that HP level than to try it NA. Not saying it can't be done, but just how streetable it will be in the end is another story. And are we talking rwhp or at the crank? I'm about 550 at the crank VERY streetable. But if your talking 600 rwhp on pump gas, I don't know long hauls I'd plan.

fuelie heads used to be the thing Maybe not for 600hp, seems now that the cost of aluminum heads have come down and no one likes cast iron anymore. Is there that much diffrence in fuelie heads that have been ported / polished with larger valves, push rod retainers and screw in studs than aluminum.

my opinion cast iron are more durable.

Cubic inches and rectangular dollars if you're sticking with Gen 1 stuff.
Stroke a 6.2L block to make a 427, outta the box L92 heads and a decent cam will get you over 600hp with an LS family engine, it'll be a lot cheaper than the Gen 1, too.

Re: What would it take to build a 600hp NA, SB?

Building an affordable 600 hp "pump gas" combo will be extremely difficult if you mean 93 octane. Good thing the pumps around here offer 110 octane. That makes it easy.

Good luck.
