taking the EASY route, get the entire long block you will need the cobra/mach1 harness (or cut up your old one) intake, and headers/manifolds. all the accessories will bolt up the same, except possibly the alternator, may need the mach bracket for that.. unsure there. unless you are getting a good deal, get a cobra block and add on your own top end items to make it better for not much extra cost.
