Re: Big block 402 help needed
I wonder if the diameter of this section is too small and letting to much oil to bypass or maybe the groove is not located right and blocking the oil port.

Might pull and check the gear and the part that is supposed to engage the oil pump. Possible something got made wrong. QA isn't what it used to be.

Maybe you have a grooved cam bearing.
