he said short blocks, so yes in a sense they are all the same, long block however isnt due to 96-98 having non pi heads and 99-04 having pi heads. and yes coil packs from 98-04, yet 98 w/cops had non pi heads

I understand that when you put PI heads on a non PI engine it raises the compression to about 10:5-1. So on '99s and up they already have that ratio?

Pistons are different as well. Non PI are 11cc Dished with a 51cc combustion chamber and PI heads are 17cc with a 42cc combustion chamber.
