Vintage motors and other applications with hard to find pistons can have up to .004� of PC-9� added to the diameter of a piston to tighten piston to wall clearance. Jeepmon said: "When I looked into having my pistons coated.. I think the coating is good for .002 per side which will only be .004 total... and there's nothing to prevent the coating from scratching off.. " __________ Sounds fine for a restoration, but do you really want to add that much thickness in a performance application? Doesn't sound like you're that convinced that it's the way to go. When I said "Good coatings" I intended it to mean a high performance app. Maybe should have made that more clear.

You're probably right...!! I'm the first one to admit I dont know enough about building motors... or race motors to state any facts.. I was just passing along information I found elsewhere.. 73 Duster 360 stroker http://www.cardomain.com/ride/2594657
