what else needed 400 rwhp

afr 185's an a better cam to match your combo, 30lb injectors, longtubes and maybe a dyno tune. :D

I've seen 306's that made close to what your making with that 347 it's do able without switching to carb.

i bet you could push 400 out of a 347... the most important part of building a motor is selecting the cam that matches what your engine will put out (according to flow #'s and such) There are cams out there that you can buy, but nothing will be better than a custom ground. MY friend is running a sbc 355 (bored .030 over) na. with a cam that the machinest who put it together specd, and hes pushing 420hp on a 600cfm carb. So id think a 347 fulie could easily get there, and stomp on that 355. :shrug: :rlaugh:

GEt some afr 185 heads and some long tube headers a friend of mine has pretty much the same set up as u with 42# injectors and 185 head with a little portmatching to match the ported preformer intake and long tubes and he is making around 420 to the rear wheels. hope that helps you out :nice:
 
Whats wrong with his cam? MM&FF did a cylinder head test with a 331 stroker, AFR 185 heads, XE274HR (just like his), and a performer Rpm intake with 650 carb and made 450 hp! they said the cam was perfect for the motor.....

i dont' think there is much diffrence between a 331 and 347..... :shrug:

i have the same cam in mine also....but i haven't ran the motor yet...i have the EXACT COMBO listed above.........

P.S.-J dallen....hows that cam sound at idle??
 
when was the last chip upgrade or re-burn? just wondering if its hindering performance more than helping. The chips are a funny thing and have to be pretty dead on to maximize performance.....ya know. You have a hell of a set-up, but your #'s look low to me, times as well as hp. Where the #'s documented on a dynojet or what?
