340 Max HP Potential with X/J heads?

moparodbuster said

Does anyone have experience stroking a .40 over 340 with a 4.00 forged crankshaft, scat rods, 585 lift cam, Victor 340 intake, 11:1 Diamonds, worked 950 Holley, etc using ported J heads? What would be the HP limitation by using these?
Only asking because I have the chance to save over $1k by buying a pair of stock J's instead of using Eddy RPM's.
Thanks in advance.

It isnt hard or easy to make a set of j heads support 550 hp, just patience and the right cam. Its math, put $600 - $1000 into heads that cost next to nothing -build around them-
Or 1600 rpm heads , porting extra.

If cheap head flows the same as higher priced head.... you did good.
Save weight by going to a manual steer box, aluminum master cylinder, small alternator, aluminum radiator, chuck the clutch fan n go electric or light flex etc...
