[YENKO DEUCE REGISTRY]

Let me revise your spec's a little! (July is too late)

The ideal block should have a cast date between mid-may and the 2nd week of June, and should have an assy date of the 2nd week of June. However, a block with a cast date as early as March with an assy date post-March would suffice. No 1980 blocks with the small pad!

The water pump is a #692 and can be found somewhat easily by going to the local junkyard, as they came on thousands of small blocks. The best yard? Geeses Auto Salvage in Perkasie, although I hear they now charge a $2 cover charge to offset insurance costs.

If you need a crank and rods, it's probably best that you buy them new, directly from GM via the Performance Parts catalog. It's difficult to buy that stuff used and feel comfortable that it's not hurt.
