will need the timing cover as well to match the water pump and then an elec fuel pump.no hole for fuel pump on a magnum and you may have to remove the eccentric to clear the timing cover.need the belt tensioner/s.

the power steering pump will have to be played with so it doesnt over press your old school box(rack pumps are more powerfull)one of the mopar mags has an artichle on this.

im not sure if some of the extra head bolts on the front of the mag heads are ness for the brakcetry,look it over.

fyi ive heard peaple have trouble with the mag belt drive while roadcoursing.rocket restorations blew several engines up in thier mag powered roadracer due to spitting out belts on a roadcourse.
