the conversion is to a 350, bored out .030 over to clean it up, flat top pistons to take up the compression a bit and a TH-350 trans adapted to the NP231 because the AX5 would not hold the 350.

A full rewire of the Jeep end to end is also in order and to top it off I made a steel flat dash to get rid of the plastic and make way for good gauges.

It should get down the highway a little better now. I hope that you have addressed the Dana 35 rear end so it continues to go down the highway.
