318 300-350 hp goal : now 323 cu.in

340s made 299 hp ; what all the infos says and 314 hp with the 71 thermoquad and intake , so with this combination and j heads with big 2.02 x 1.60 with a decent cam or even the 340 cam. And headers, pretty sure i can break the 300 hp mark and torque too. Dont want to spend a fortune right now , thats why i bought a fresh 323 cubic inch engine . dont think that 17 cubes will really make a difference.
