I have a 700R4, but it's for a 4WD truck. Thanks for the replies. I'm mostly worried about clearance for the headers, and that $600.00 aluminum radiator. I was going to put this '71 cab & front clip on a built '86 GMC 4x4 frame. I've decided to keep the '71 stock except the engine. I love my 454, and I know it will breath new life in my C20.
