have a 318(out of a 78 dodge pick up) in my 87 yj thats bolted to the tf999 and stock transfer case dont know if theres any adapters cause i didnt do the swap. but it looks like its just bolted right to the tranny. Ill probably find out when i pull the engine to freshen it up a bit. definatly has good power though even though its just a 2 barrel carb, was looking around for a intake and 4 barrel to swap it out but money is very limited seeing how im planning on rebuilding the rear end or doing an axle swap.
It looks like its the stock radiator but i dont know if they came in 3 row but its cooling exept for the fact that it leaks. bottem casting on rad needs to be moved to the other side of the radiator though.
Have you found out if there are any adaptors between your 318 and your
tf999? do you have any pics? of the engine bay as well as the underside of the jeep where the motor and tranny mate up?
