To rebuild or not to rebuild?
I am in the middle of doing a 4.0 swap into mt 81 cj5. I have the 4.0 on a motor stand and had plans of rebuilding it. I have it all tore down and was looking in the cylinders. I can still see the factory cross hatching on the cylinder walls. all the rod bearing dont have any play in them. should I rebuild it anyway just to be safe? the donor cherokee had 160,000 miles and ran fine. I dont want to do the stroker yet im just getting the 4.0 in and ready to go for the summer. Maybe take my time and build a stroker while I can still run the jeep. any thoughts? advice?
