Newbie 318 piston question

Theres nothing majic about it. Every successful performance small block out there from any US manufacturer in the classic era has at least a 4 inch bore. Now you all of a sudden know better than the folks who designed those engines? You do see what Vizard and Andy wood are going through trying to make a 318 into a performance engine no? they've hit a wall fairly quick.

no all of a sudden at all. check out the bore sizes of gm ls motors. the 4.8,5.3 and 5.7 are all from a lot to a bit smaller than a 318. nobody says they can't perform with small bores do they? my point was the 318 isn't much smaller than the 4" bore everyone seems to think is the benchmark for performance :poke: :thumbsup:
