Steve, yes, I remember meeting you at the first fling, the only one that I attended.

Yes, all those parts are mine. Ive been thinking about a project down the road for my car. I would like to go with fuel injection, which fuel injection system I will use, I don't know at this time. Maybe next winter I will work on it.

The coated pistons help with detonation by eliminating hot spots on the piston, which set off detonation. The coated pistons also help to some degree with heat transfer to the piston, to help with too-lean conditions resulting in too high combustion temps. For the extra $50, I figured it couldn't hurt. And, it may have paid for itself already, as I ran the car last year's R&G in a too lean condition on the road race and drag course, and I think my engine is still OK. I may check a leak down test to be sure, but the engine isn't smoking or doing anything weird.

I also saw a test in one of the mags I get about a wide band A:F meter that works really good. I had my exhaust system made from the beginning with O2 sensor ports in the collectors, for this purpose, especially if I end up going with fuel injection.
