Just got my 1st jeep, needs some work. Here is my thoughts of upgrades: Change head to 4.0, add motorcraft 2100 carb, add header, install HEI dist. Let me say this, converting to MPI: to expensive, out of budget. Correct me if I am wrong, adding 4.0 head gives me more highend torque, motorcraft 2100 carb seems to have the best reviews, These all seem to be simple enough changes.
