Billy, RIF! (R)eading (I)s (F)undamental. I said to rev it. That last part is to counter guys who say "i run a 340 with a 4" crank..." or similar 360s. Keeping the 360 displacement just means the power at a higher peak. I find a lot of guys like to say "I built a 360.." when in reality, it's a 408. That's what I meant. Little touchy on the stroking deal, arent we...lol?
MIKESDUSTER has a 340 that has ported J heads on it. With a longer (360 is 3.58 ) stroke, and a solid cam, it would easily top 500 hp without Edelbrocks or W2s. But, the peaks will be in the 4500 and 6000 rpm ranges, which IMO is a little high for most street cars. It can make for a soft feel driving around town with the required convertor, and numerically high rear gear ratio.
