I have a 84 mitsu mighty max 4d55. It was given to me with a cracked head. I replaced the head with a new one and still low compression. I replaced the rings and lower end. still low compression. engine kinda starts with starting fluid. Not to familiar with these engines. want to do an engine swap. possibly 4.3 or small block mopar. I read that it has been done. just need the details. it is a 4x4. can i use the same trans on one of these engines. its 5 spd. don't know which road to take. i've already drop some money on the head, rings and bearings. I will be posting some of those parts online to sell. please advice. I want it to be on a budget. thanks
