..."I searched and couldnt find what I was looking for. I was wondering if a chevy 4.3 v6 or a 350 chevy will bolt in place of the 2.8 -?"
....Search and search again in the
archives useing terms like "Chevy 350 engine swap"-If you had searched you would have found that this topic and subject comes up almost on a daily basis-Good luck
I also had an older blown up tired-out Jeep XJ 2.8 liter engine and elected to go the Chevy 4.3 route.... but,....... what the heck ..if you're going though the effort and expense of the Chevy 4.3 liter ..it is about the same as going on upwards to the Chevy 5.7 liter blocks for about triple the horsepower increase from the older Jeep XJ 2.5 liter or XJ 2.8 liter engine blocks-
