does anyone know how hard it would be to put a 383 and a 350 trans in my cj5. it currently has a 304 with a t15 in it . the trany is toast. i can get the motor and tranny for 400$. the stroker is already built and i can get a chevy transfer case for it for free.is it cheaper than a tranny rebuild? i will not sell the jeep so i have to do something!
