@Henry Schmidt:
Looks very like the engine in this car you build:

You used in this engine the AA cilinders, probably with Cryogenic treatment.
How is your experience now with these AA cilinders, and is the Cryo necessary?
Sounds like a great running engine; a lot of difference with the engine I described (2.4S spec w/ 2.2S pistons)?
