Ideal Drag Race Bore and Stroke

This guy is too much, makes wild *** assumptions then has strawman arguments.

No one is saying a smaller bore is better, just for 200-400 or so hp you don't need a huge bore a 318 bore is more than adequate, even a 273 bore could handle those power levels without too much work, I bet the block strength is more of a limiting factor than a 318 bore size.

Available bores 3.625, 3.91, 4.00, 4.04, 4.125, 4.185, 4.25, 4.32, 4.34 why is 4" the magic choice ?

A 3.98 bore is half way between a 273 and a 400 bore, 318/360/340 are all not too far from being a mid size bore from our available options, better than a 273 worst than every big block.
