Good job Eric. O.K., we have the reciprocating assembly nailed down. I'm all for limiting the revs to 6,500 because then we can use a hydraulic roller cam. Now, let's choose a block.

Here's the World Product Ford Man O' War block. It can be had in several different deck heights.

And here's the Dart product. We'll have to discuss these later. I have an invitation to dinner.
