I would use a mech fuel pump adaptor from hughes and run all the 85 318 stuff on the front of it.

the t-cover swaps and the adaptor lets you run a mech fuel pump.

all the pullys/belts/pumps/brackets will work. IIRC you do have to fiddle with the alt bracket some.

the edelbrock intake with magnum bolt pattern is the intake or the cross wind

you will also want to use the magnum pilot bearing, it larger and fits in the TC snout hub of the crank but will fit the 883/883OD.

I would pop for the 2 piece at hughes and install it.
