One of those 'what HP will this make' questions

QuantumMotorsports · 05-13-2003, 11:47 AM

I have an idea myself what kind of power this combo will make, just want to see what you guys think.

'76 302 bottom end out of a bronco (new bearings, rings, and honed, valve reliefs cut)
Comp cams 292H (.534 lift, 244 duration at .050 lift)
GT-40P heads mildly ported, high RPM valve springs
Weiand Stealth intake port matched
Holly 4150HP 650cfm carb
1 3/4" long tube headers
Two single chamber flowmasters

Tell me what you think. Thanks.

HP: 330 @ 6500
TQ: 315 @5000

I ran it through perf trend analyzer and that what it showed. I had to guess at the heads cause doesn't show gt-40p heads there.
