Lifter clearancing

I have no experience ;) Ill say that first are foremost, but what I have read(that is ALOT), especially in my stroker book, is that a roller cam is NOT suggested in these blocks for that specific reasoning, do not try to clearance it either, you WILL hit water. The only solutions I know of are having shady dell speed shop clearance it, as they apparently are doing now, or use Jesel tappets with the special tappet bushing that have a keyway and dont use a tie bar. It is supposed to work very well, but comes with a big $$$ price tag. The only other option is to use ISKY tappets that have the tie bar located below the seat for the pushrod. If you grind, you will hit water ;) Dont waste your block, do it right once.

Good luck!
