Put a 4.0 in my cj5!!?
I have a 74 cj5 and recently tore the engine down for a rebuild as it has been ran out of oil in the past, had coolant in the oil and timing chain about to rub through the cover. I took all the parts to the machine shop and a back to factory-ish rebuild is going to cost me about 1400 with a new carb. I was looking to get it on the road in the meantime and was looking for a used engine. The best I've come across is a 4.2 that has sat for 10 years but "ran" when put away. I can get it for two hundred. Being a tech I would want to re ring it at least and put new bearings in and that's another two hundred. I see far more used 4.0s how much work is it and what would need to put a 4.0 in my cj5? Would it work with my three speed trans?
