You know, if you really want to have an adjustable timing gear set, you wouldn't have to start from scratch. Just take a standard gear set and machine the center of the cam gear out. Then make a new hub that bolts to the cam and to the remaining part of the cam gear. Might not look as fancy as the S. American one, but would work as well. If you were in the parts selling business it would keep the price down too.

Also, back to Tom's original request for feedback on the timing cover - Why not make the 1" diameter boss larger in diameter. Make it fit a Hilborn fuel injection pump.
