Yeah, actually i think the wisecos would have more compression cuz they seem to hold up better. Maybe its just my motor or combination of mods , but with that cutout in the piston, when its up against the head there is a lil more room with the dish in the piston so compression is lowered, but think, its still gonna increase when you go from a bad top end to a new set of superstocks, im not tryin to argue because everyone is going to have their own opinion and that is respectable, but everyone is going to have different results with them. All i said is that i wont go back with them, but i never told ne one they couldn't run them...
