lowering a 383 into A-body

thanks for your reply Jim. okay, i'm normally hoisting the engine and trans up high enough to get across the front radiator cross piece, then pushing trans down into the tunnel (because of the overall length) to get the whole assembly past the cross piece, so i can begin lowering it. now you are saying start with the engine lower, are you talking about doing it without the k-frame, or do you cut the cross piece out and reweld later? thanks Gerry
