Thanks for your thoughts. The truck has a small block in it now and when you set the old hemi next to a small block it looks more massive. The heads are larger and I was concerned that there might not be enough room for headers to clear the frame without having to set the engine up much higher. I am not registered on hamb so I can't see 65standard's build but I take it he did put a Hemi in his truck. At any rate, thanks!
