Yep, we are reading the same thread It is a good one...
Of course a 347 can hit over 400rwhp, but I have not seen many , if any at all hit 400 rwhp with AFR 165's and similar parts to match.
The ls1 is hitting well over 400 rwhp with stock heads (similar to AFR 165's), and a stock intake and full accessories
The 347's with over 400 rwhp, all have larger heads than the ls1, larger camshafts, and I am not to sure on the intake and a comparison between it. I will have to look into that sometime later.
I never questioned that the 347 could hit 400 rwhp Pokageek, but I see ls1's doing more with less, rather than the other way around. There are TONS of h/c ls1's with over 450 rwhp. I do not see to many 347's strapping down that kind of power on a chassis dyno with the same type compression/powerband/accessories as the ls1 combinations out there.
But hey, I love the 331 and 347 and they both can get you moving in a hurry
Grady - Nope, I think your comparison graphs are great because you provide so many varieties for us to put together. Keep it up...
Anyways, off to study
I couldn't tolerate driving anything that the LS? engines came in. (Poor build quality/engineering/ergonomics.) I'll take my wimpy little 302 and my SOLID Mustang, everytime!
