Iso /6 hardened oil pump drive gear

Bill, what are your intentions for this engine? Even Dutra himself has basically said they'll be ok unless you run like a thick 50 weight racing oil and spin high RPM. Is that what you intend to do? If not and all you plan to run is 10/30 and a street car, I'll most likely be fine.

So basically here is the build and philosophy of use. .440 comp cam, cut the head 100 thousandths, ported the head, offy 4 bbl intake and mopar header. Full garage rebuild bearings and rings, put a new oem style oil pump in it,

I mainly just want to drive the thing and ill get on it here and there but I honestly Dont thin ill ever spin the engine over 4800 because I doubt the head will flow enough to accommodate a higher rmp than that
