My 572 is 10.5-1.
Comp cams
.421 lobe lift
Stage V rockers
.674 I .657 E
264* 270* @ .050
112 LSA

Lifters have Oil fed rollers, but not push-rod oiling.
Smith Bros PRs
Comp 943 springs
World alum block comes bushed with oil hole.

I do not have a lot of street miles on the engine yet, and only a few passes 1/8th mile.






Any idea what size the lifter bushing oil hole is?
