Well, common sense dictates that under acceleration, the oil wants to be 
in the rear of the pan, so what better place for the oil pump.  On the 
other hand, since the camshaft is driven from the front, common sense also 
dictates that the distributor and oil pump should be driven from the front 
of the cam.  Chevy's had a problem with the cam twisting, especially when 
a high volume/pressure oil pump was used, causing erratic spark timing.

When I was much younger, my brother and I both had big block Mustangs.  I 
ran a tunnel port 427 while he had a 429 SCJ.  The Chevy's really didn't 
have a chance.

BTW, a E. bleheri may use a crank triggered system, with a small coil 
attached to each spark plug.
