The nutter bypass is only for for 258 with the computer controlled carb. You do not need it on the 360. What you will need is a flywheel specifically balanced for the 360, it it came with one use it the 258 will fit but will cause vibration. Also you will need the complete motor mounts from the V8 on a CJ the 6 and 8 rubber mount parts are different and one of the steel mount that attach to the frame is also different, I think the passenger side is the one but I,m out of town and cant check. Also V8s make a lot more heat so the 6 prob came with a 2 core rad and you will need a 3 core at least. Just order one from a 304 equipped 1980 cj7 or maybe your local rad shop will be able to modify yours. That T4 will blow up, it is just a question of when. Consider looking for a T176 or a T18, go to Novak adapters they have lots of info on that stuff. Having said all this, you will love the V8 it will really wake up your jeep, except of course for the gas mileage.
