Well I came across a free 77 2wd with a fresh 454. I am gonna put the engine in my burb, what exactly will I need? What problems will show up in the middle of the swap? I am sure it is a typical motor swap, but I just want to be sure. Will my 700r4 be alright? I know they are not great for handling tq, is shifts great, has about 60k on it.
