451 stroker, cut the crank or block?

No oil mods are part of a typical rebuild. Only some of the performance shops I know of do anything either. The mopar oiling system is pretty good on it's own in terms of volume and delivery. At least until you get into higher sustained rpms. Like over 6K. With proper clearances even a stock oil system can keep things together at 6500.


This has been my experience. 70# spring and go-go-go.
