Hemis came with the big pump so if it ain’t on there someone changed it out. Dent in wrong pan, first place to look for pickup damage. Every Hemi we had carried 40 psi at idle with those ‘big’ bearings. Also Try another filter. Who knows what’s been done to the engine in those first few years though. I’d have that pan off tonite.
Nice car though, I have a 66 Belvedere Hemi 4 speed trying to get together. Wish you luck and hope it’s an easy fix.
Huh? Hemis had their own pans and pickups but the pump itself was the same as other RB motors. I don’t think Mopar put a HV pump on any production vehicle?
