Re: 318 engine swap in 1980 CJ7
If the Dodge 318 is a 5.2 magnum engine, it should just bolt directly to the bellhousing that Dodge uses in the Ram trucks. This combo is popular in the Ram trucks and B series vans. This bellhousing uses the same hydrolic master/slave setup that the '95 and up Wranglers use, so that shouldn't be a problem. The Dana 300 should bolt to the NV-4500 without any problems, and you use the lightweight Dodge version with the 23 spline output. I started to put a stroker 4.5 L six into my CJ-7, but then ran across a 5.9 Magnum, and that is going in next. The motor mounts that Jeep uses in the Grands have a high mount, and I don't think they will work, but the Ram truck mounts are lower on the block, and look like they will work with a special made perch. As far as wiring the fuel injection, is should be easy if you stick to the '94-'95 harness and SBEC controller. This system is almost exactly the same as the MPFI kit that Hesco sells, but with 2 more cylinders. I am trying to wire a '98 JTEC controller, and use a '98 Grand Cherokee's instrument cluster. The reason for this is I have the controller, and all of the sensors on my new 5.9 came from a '98. I should have the ability to re-flash my PCM with newer updates from Chrysler.
