Might wanna check that. Theres no reason why the same bolts used in a different position should have a higher torque spec.

4 bolt SBC mains go 70ft/lbs on the inners and 65ft/lbs on the outers

BBC use 110 on all the mains.

I believe so, the oil pump is in the rear, so the front main survives by oil supplied through the crank, but need to verify that for sure (been a while).

Ah, I thought when you said "other engines" like a 350 you were refering to chevy stuff. My bad. I misread it.

I figured, I only included the 350 comment because he never stated 455, he just said "Olds", there are quite a few 350 Oldsmobile's in jets out there.... ;)

No harm no foul... :beer:
