I can't get my head round this, i was told a .625/.625 275/283 on a 107 was too big for my 470 with 440-1 heads with bowl and guide work, same comp, and yet here's a motor with a .776/764 279/289 at 0.50 and it make all this power, surely it should be a mutt down low but it makes over 700 hp at 6000 ?

Told by who? I run a .680-.660 Isky solid roller w/276-281 @ .050 w/lowly home ported RPM`s and 12.1.1 compression and it runs/drives just fine on the street..............
