Looks rather good....

Here you can see Garys old engine block with the crank resting on top. Off to the right you can see a piston and the AEG625 rods and the ARP bolt set.

Inside of the piston

You can see the black coating which maximises the heat rejection.

Ceramic coated pistons

From Camcoat (ask for Peter...)

Three coatings:

The grey coating is a moly-disulphide dry-film lubricant coating reduces frictional losses and reduces the chances of galling and scuffing.

Inside the piston the black coating is a thermal dispersant coating inside the piston maximises the amount of heat rejection from the metal.

On to the top is a thin, highly polished ceramic coating on the crown insulates the piston. The reflective surface reduces carbon build-up and increases the rate of combustion.
