I dynoed 304rwhp/324rwtq with ported E7's, an e-cam and an edelbrock performer rpm manifold and no crazy tricks (smog pump bypassed).
Tell us more about the head's specifics and flow (who did them too) and the cam.
I'd love to see the dyno curve if that is possible also. That is about the most I've seen claimed from a non-pro race engine.
I'm thinking it's a carb motor.
I made 262rwhp 328rwtq with Thumpers, Performer RPM intake and a .545/.545 218/224 114 cam through an AOD. It still had a/c and the stock fan too.
GT40 Valves!
you said before you had stock valves...
congrats you car is pretty fast for what you have!
but they make you hole-shot and ET real nice.........that's why dyno testing for an auto is all about A/F - take it to the track for the real numbers imo.
IMHO the parts you listed will get ya in the 240whp range. I agree w/ Dman your going to have to change more than that to get 300rwhp. Most ppl w/ the trickflow top end kit on a 302 are making 290-300rwhp. 50 or 60whp is not easy to come by without major changes or nitrous.
cleanLX has 230cfm pro-ported E7 heads (Power Heads with extra work), a custom Buddy Rawls cam and my ported stock intake with two uppers - a long and shorter runner version with long tubes. With a 60mm TB and a ported stock length upper he put down 280RWHP/330RWTQ. Switched to the shorter upper version intake and a 65mm TB and made 292RWHP/325RWTQ. That's the most I've seen documented (dynos) in a non-race engine running stock ported parts so far. Maybe others have similar results and will report.
