I have a 77 CJ5 that has an issue with the current 258 engine. I think the cam might be bent or perhaps the bearings are bad. The last time it started it broke the teeth off of the distributor. Anyway thinking of swapping to a 304 or 360. Does anyone have any suggestions? Will it bolt up to the existing transmission? Am aware that engine mounts will have to be moved. Any info would be great. Also I live in cumming, Ga anyone know of any good used motor shops, etc. Thanks, T.
