318 low-rpm performance ........... for the NEWBE

If you build a 318 340 snd 360 with stock bore and 3.31" vs 3.58" vs 4.00" cranks, would be 318 vs 333 vs 340, 344 vs 360 vs 367, 384 vs 402 vs 410, are we really talking big differences between bore cid potential? Especially comparing 318 vs 360 blocks with same crank there's very little difference between the two.

Surprised with all the 408 strokers that a turned down 360 crank for a 344-360, 318 strokers aren't popular. Guess might as well go 4".
