I just recently tore down a 355 with .125 dome pistons and all the pistons are covered with a layer of carbon. This motor ran in a hobby stock class on a 3/8 mile track. Motor was never ran above 6000 rpm.
I think I understand why they are carbon covered, but I would like to hear from some others as to what they think.

Running a little rich but a little rich is better then a hole in the piston.

Yep,you can lean it out for a nice clean piston,it may also clean the top off of one too

Thanks guys. That is what I suspected, and I agree. A little rich is better that a hole in the piston.
Thanks again
