I picked up a basketcase CJ7 which included a completely rebuilt Ford 302. The engine has an Autolite 2V carb and I would like to replace it with MPI.

I know I can pull an MPI system off of a late model 302 with EEC-IV but that means heads, computer and wiring harness ... you know ... major mods. I was just trying to keep it simple.

By the way, the Accel unit is only made for Chevy engines.

I pulled a beater 351 out of a truck and put in a 5.0L and I didn't notice anything about the heads that was specific to EFI - the injectors are in the manifold. I threw away the manifold, plenum, and throttle body when I changed it to the car style, because they were so cheap to buy in the junkyard. Check near you. It may be cheaper than you think.

Re: Aftermarket fuel injection
 
Sorry to be a little off topic, but, is there any difference between the FI on a 302 and 351? Could I use a manifold and injectors from a 302 to change my 351 to FI? Thanks

The Upper plenum is the same but the 302 and 351 intakes are not interchangable because of the 351s increased deck height. So you'll have to find a 351 lower. Also if the setup is Speed Density, I would think that running a 351 with a 302 computer may not make the best running motor. Speed density will compensate - to a extent, I wouldn't know if it would matter to much.

Some 302's use a smaller (different color) injector. Installing them on a 351 may cause them to burn out frequently because the EEC will hold them open longer, generating more heat in their coils.
