Any recommends on suppliers for non-standard compression ratio pistons? Looking for 9:1 for an 0-320. They will go in Superior through-hardened cylinders.

Part number you need is (ASC 15357F) This is a forged CNC machined 9:1 piston for a 320 Lycoming. They also have a 9:5 piston if your interested. Combustion Technologies is who makes pistons for Superior the last I new. They also build many of the Winston Cup NASCAR pistons. I had a set of custom 10:5 pistons made and they looked to nice to put inside an engine. Very quality part. Hope this helps, AJ

I used lycon to get NFS pistons, not super high compression, but easier to get VERY close balance. As I recall, total to port barrels and add custom pistons was only a few hundred bucks per jug.
