Title: Melling M63HV oil pump identification
Post by: Cuda4u on December 28, 2018 - 01:17:41 PM
Stamped on Melling oil pump is M63
If it is the HV version would it not be M63HV?

I don't know which one the M63 is, but for a small block, the stock pump is a M72 and the high volume one is M72HV and it's cast into the pump housing over the pick up tube intake port. Hope that helps.  :cheers:
