Just wanting to hear oppinions on the teflon coating on pistons. I have never used any on the teflon coated pistons and am getting ready to stroke a couple of LT1s. Seems to me that the coated pistons would be better for friction, but I am concerned about the longivity. Has anyone ever used the pistons over an extensive periond of time and mileage, and how do they hold up?
Stands to reason that if the coating flakes off that it would get into the oiling system and who knows. Also I am concerned that it the coating wears or flakes off that it would cause more than desirable piston to wall clearance.
In my stock LT1s that I have, both at least 150,000 miles, you can still see the hone markings in the cylinder walls and the machine grooves on the pistons show hardly any wear at all if any. Not bad for over 150,000 miles. I might add that these engines came out of Police cars. They also sit and idle for hours on end that doesn't show up on the speedo.
What,s your thought on this?

Thanks, Ed
