Bob Book (of carburetor fame) is trying to talk Dick Maskin into building SBM race blocks.

This is the thread on Facebook where he is asking for comments:

If you are asking "why does Bob care", he builds engines for Australian Pro Stock racers who use small blocks. He is at horsepower levels above the capacity of the R3/R4 blocks and wants something that will last.

If you are interested go to Facebook and add your $.02. If not never mind.
