Building a street 451 low deck engine.

What are the pros & cans of the different oil pup drives out there?

Is the Mopar Performance one the best option? (about $100)

Are the Mellings and Sealed Power ones acceptable? (about $50)

They all seem to have hardened shafts.

The Mopar one has a pinned on gear, is that preferable?

Will be running a Flat Tappeet Solid Lifter Cam.

Opinions?

Kayse can't keep up at all now. lol
