Re: Stock Oil Pan for 496?
No, it swallowed my 496 rotating assembly with no grinding at all!
I did use truck rods so had to cam-cut my crank b/c I missed Lunati's tell me to use at least 1/4" longer custom rods to help balancing it but I don't think that matters.
I honestly think it would swallow a 4.375" crank with minimal grinding too after sticking a piece of bent "tie-wire" down it in several tight spots....
I did grind on my oil pump for nut clearance and I did grind new valve relief's in the top of each cylinder like it shoulda had before boring if it would have been a hi-po block.
Matched a headgasket outline and down about an 1/8th inch is all on both the intake and exhaust.
