Turbo City (http://www.turbocity.com) has a nice fuel injection kit for older vehicles that uses GM computers, sensors, and throttle bodies.
Holley also makes the Pro-Jection, but I've heard mixed things about it.
The best thing to do might be to swap in a late model 302. Pick up the computer, harness, and all the other little things you need out of a wrecked car or truck. You can also get the harness from Ford Motorsport and a few aftermarket companies as well.
I would suggest finding a wrecked late model 5.0 Mustang for a donor motor and tranny. One of the best sources around for this kind of swap is www.windsorfox.com. You can send them your harness for retro-fit to your application. Please don't ruin your P.U. with a GM.
I am thinking of using some sortof fuel injection
in my '61econ.p.u. hot rod I'm building. Icould use
all the help I can get!!
I have a complete '89 5.0 HO fuel injection set up (computer, harness, brackets, plunium, intake) less a couple of fuel injectors. The guy I bought from changed the wiring for the firing order to a standard 5.0. I was going to use this on my project '61 but have chosen to sell it also. If interested email me at email@example.com
