Thread: HP & Torq

You are limited by the TB heads. If you can get everything you need to use Vortec heads I would go that route. I think 380Hp on the dyno is pushing it. Without the dyno sheet to prove it he's just talking smack. I have a stock '94 Silverado, 350 TBI, I'm guessing it has 250Hp and pretty much is done at 4000 RPM, I know a cam will not add 130HP. Just my 2 cents.

Exactly what I was thinking. The heads will work well in an idle to 4000 rpm motor. That's what they were designed to do.

A while back, I tried to get all the EQ cylinder heads together in one place, but there is conflicting information and so many different part numbers that it made me nuts and I quit trying to catalog them.

I thought maybe the CH350C would be a decent street head. It supposedly has 180cc intake runners and 62cc chambers, but I found the flow numbers on them and they look much inferior to the L31 Chevy heads.

I guess when push comes to shove, for a zippy 350 street motor, it's gonna be hard to beat these cast iron 170cc Pro Torker heads from Racing Head Service....
