I'm building another engine and the melling hv oil pump i bought won't clear the main studs, take in mind i have main support and studs are a little longer than usual, i tried clearancing the pump but its still not enough (actually went to far and made a hole in the oilpump which i have to weld now to fix). Was wondering if i could grind the stud down if anyone else has any ideas let me know thanx.
