ok. finally starting work on my 93 lightning. motor is out. motor had 68000 original miles. had a rear main leak so pulled it. while i got it out wanted to freshen it up. have a set of trick flow track heats for it and trick flow cam for it. plans for motor are honing cylinders, new piston rings, bearings etc. i have a vortech v1 kit for a mustang that i never used. need brackets to begin with. looking for a mass air conversion for it. need part numbers. also fuel system upgrades. also need mild suspensions up grades.would also like to put full length headers on it with full exhaust. any pointers and info out there?
If the rear main is leaking, chances are, the thrust bearing is worn. I wouldn't hone/re-ring it unless it needed it with what little mileage you have on it. What I would recommend though is to upgrade the hardware, ARP main, rod and head bolts, and install a Canton main girdle. Fuel system upgrades depend on how much power you plan to make. With that said, you don't need to gut the stock fuel system with a V-1. A dual pump trigger and a 255lph will support a ton of power and should get you into the 11's with the correct injectors and tuning.
Look around the nloc.net for a set of Pickrel headers and possibly and exhaust system. Otherwise you'll have to buy a set of truck headers and do a little welding/fabrication.
You will need something to get the rear end under control too to keep it from binding. LFP (Lightning Force Performance) makes the best traction bars available for the GEN 1's, however, you may have to wait a bit to get them though. The factory LSD is weak and notorious for breaking off friction plates. An Eaton Locker or True-Trac upgrade would be the way to go.
Last but not least, the transmission. This is another very important component to pay close attention to. It is not uncommon for an E4OD to balloon/destroy a converter, and if/when that happens, it can take out the rest of the transmission. I would recommend replacing the factory cooler with a Powerstroke trans cooler from the late 90's to early 2000, run a deep pan with a trans temp gauge and install a Punisher Valve body to firm up the shifts.
