I scrapped the idea for a stock internaled 302 and am just going for a 347 since its going to be about 2,500-3,000$ more...money well spent in my opinion. I can rev it higher and I will get more power with the right combo...I have an idea of what makes power on these 302 base motors, but what heads would work well? I was thinking trick flow renegade 225cc, or trick flow hi-port 225cc or even a good set of ported canfields. Custom solid roller will be from FTI. I heard he does great work and that solid rollers are better for high rpms? Looking to spin about 7500rpms. So what heads? Also, I heard shaft mount rockers are a must for spinning that high? This will be a daily street car...so keep that in mind. I'm not sure on the fine details so help me out. I know ill use a gforce dog-cut T5 and I will still retain EFI. Ultimate goal is to run a lowwww 10. Maybe a 10.2-10.4? Is that possible? I've seen 347s with Victor Jr. Comp cams solid roller and a super Vic run 10.9s easy...so custom stuff would get me close right? Thanks.
