I had a piston come apart in my "A". No idea on the history of the engine or the piston source as I've only had it a couple of years. The pistons look very new, at least the parts in the bottom of the oil pan do.

I intend to replace it myself...what do I need to do to ensure I have the most reliable engine possible?

Any recommendations on a dial bore guage, or an appropriate way to accurately measure the cylinder bore?

Hone to .035 clearance between cylinder and piston (that distance split between the two sides)?

Anyone have tips on honing?

I'll get a scale and balance all rods and pistons.

I've done work on auto and aircraft engines before, but never honed cylinders.

I do have Les' book and will read before proceeding.
