Don't know if you ever saw the Ron Bohn Vortec 4200. It is more high tech than anyone could imagine. I think the only factory part left on it is the block and heads, which were all massaged quite well.

Here's one I just came across, A 4 BBL manifold and Dizzy on a 4200. The Dizzy takes the place of the PS pump.
