The shop I'm looking at is charging $55 for a torque plate bore/hone. It isn't so much the power aspect (the 350 produces 2.5x the power of the 235 it replaced) as it is I would like the engine to run as long as possible as well as possible before another teardown. I think I will, the shop is known for their performance builds, and spending a little extra for a better job sounds like an investment.

While I'm here, does anyone have experience with electric water pumps? I am considering it for the space saving aspect.
