What lifters were you running ?

Crane ultrapro.842

Tried Cranes in one motor, they were undersize for the lifter bores and it lost oil pressure, we had our best luck with the Crower 66291H. They may be better I don't know.

You still running bushing lifters?

No, that was several motors ago when I tried the groove lock lifters.

How did they hold up and what would fail on them? My friend is thinking of using them I told him not to.

They were the Crowers, can't remember what destroyed them, may have been one of our spring issues. At that time is was around $600 to machine the block and a $1000 for the lifters.

You two should just call each other
