I'm about to begin an engine swap for my '38 Plymouth sedan. Being someone who likes something a little different, I've decided on the amazing 4.0 High Output Jeep six and the matching 4 speed overdrive Jeep automatic. My donor is a ‘91 Cherokee with only 65K on the clock prior to going into a ditch and messing up the bodywork. I plan to use the EFI with the computer and all. The car will get a complete rewire and 12 volt conversion. I’ll also will be adding an air/heat/defrost unit from Airtique and hope to swap in the Jeep 20 gallon gas tank as well. Just wondering if anyone has any experience with this or a similar swap. I expect quite an adventure since I've never swapped in a brain before. Any advice would be appreciated.
