stock or hv oil pump

Use only milodon The mopar performance are not near as strong. Read the description. The hex on the Mopar shaft does not hold up nor does it wear that well in the bushing. Use Steel for flat tap bronze for roller cam. The mopar performance do not hold up to RPMs with a HV pump. I have bought many for over $250 from mopar never again. China junk

1st one is a hallow pin
Second one a review says the pattern is wrong, big block reverse probably.. cause thats what i got as well one time.

Ive never had the MP fail me, though only used it with solid cams and hv pump/std pump.
Ive seen some later stock version came pinned, just not tapered and hardened..and still smaller diameter mid way up.
