I have a 91 ranger 4x4 with a 6 inch lift. Its a sick truck but I want my ranger to have more balls but keep the 5 speed stick. its got a 2.9 now but Want to convert it to a v8 and keep the 4 wheel drive standard. Whats a good motor? If its wise to change the tranny that's fine give me help but i'm stuck on keeping a standard trans.
