removing main caps

famous bob said

I wouldn`t do that to any motor that makes any horse power, we cracked # 3 main on the the hemi and everything was in excellent shape, line honed by an excellent machinist, perfect clearances. perfect crank, and it was 4 bolt mains. it will really weaken a cast iron main cap!

musta been a bad cap. i've been doing this for years and never had a problem, of course i probably wasn't making near the horse power you were either. ALL the good after market blocks come with the threaded hole in the caps for easy removal.

i have a set of high nickle 4 bolts caps if you need them?
