i think my 91 has the 6 groove pulleys. the magnum went to 7 groove so i would have to swap power steering pumps too. i wonder if its just a matter of swapping pump and reinstalling the hoses? i have been gathering parts lately. got the heads at the shop getting valve job done and springs, locks, seals and retainers intstalled. i know these heads crack and its not wise to spend money on em but they only charged me $200 to dissasemble and hot tank em. valve job and reassemble. if i blow this motor up i can use these heads over again on another short block.
