i have been toying with the idea of swaping in a 4bt into my blazer for awhile now. id like to keep the 700r4 but put in a stronger one. what do i need to complete the swap? what do i do for motor mounts? will i have to do a body lift? is there any shops in CA that can do the swap for me (don't have alot of free time)? will my 1/2 ton axles hold up?
