Some of this may be self inflicted. 1st one was a Crane in my Comp motor, the last two were in SBC Superstockers, a Comp Cams and a Crower Hi-Po. .894's in the SS. Soooo your thoughts on how many runs are safe and what about a needle lifter making more power than a bushed.
Those lifters mentioned if you are putting them in a .844 lifter bore they are to small.
Comps, Crowers and ISKY"s are .8405 to .8415 in that area and to put them in a GM lifter bore that is .844 and more so on the old blocks with short lifter bores. Running lifters in a bore with .003 clearance lifters are not happy and will show it as they looked scuff because they are using the bottom of the lifter as a cutting tool.
Morel seems to be to OEM size whether its a .842, .874 or .904
When machining for roller lifters I measure I measure each lifter and make sure bores are machined accordingly.
Here is a good link on lifters sizes between companies.
