See the piston markings, PR4 0.8 is that a specific size from the factory or what? This block only had 28k miles on it, and I wanted to reuse the pistons in another stock b18a block, but the 0.8 is bothering me, I guess I could measure them but they are not in my hands right now. Was just curious if anyone know what the 0.8 ment. (if that was oversize or what)

thanks,

Jeff
