Yj v8 Swap

Fixn to start my PROJECT.. I have a 89 Yj 6cyl auto. 4" suspension lift 2" body w/ 33's. np 208 rebuilt w/ sye. Rebuilt axles on both ends. Now the plan. I have rebuilt a sbf 302 engine,fresh rebuilt c4 with advance adapters adapter for the 208. I also purchased the adv adapter engine mounts and headers. I have thought about everything that I can think of and cant foresee any major problems. But I know I am missing something! If anyone can give me some pointers or ideas on what not to do or something I should do would be greatly appreciated. I know my stick axles are not tough but this jeep is mainly a highway driver occasional lake bed mud. Any input will be great. Pics will be loaded as progress is made.

Will the stock jeep radiator be sufficient?

I am working toward a V8 swap as well. Everything I've been told indicates that my stock radiator will be miserably insufficient, but I'm currently running a 2.5L. The custom V* conversion radiators are a bit pricey, but a lot cheaper than building a new engine.

Well the only reason I ask is in all the ole stangs that had the 302 or 289 the radiator is not in my opinion very big but I have never had any heating problems and te radiator in the yj 6cyl is actually a lil bigger than the stangs but will prolly go with a aluminum rad anyway..
