Tom,

I was under the impression that some vortec motors had the provision for mechanical fuel pumps?
Also only 8 bolts for the intake all of them vertical, vice the 12 an at an angle?

I took to the cover off the fuel pump access plate, and can clearly see the slot for the fuel pump.
maybe I need to dig more into the markings and the block.
When I get home later tonight I will get more pics and see what I can some up with as well as post the number here.
