For sale are a set of O-470-R cylinders. 5 are Superior and 1 is ECI. 2 Superior cylinders have approx. 600TTSN. 3 Superior cylinders have approx. 300 SOH. The ECI has approx. 200 TTSN. They include pistons, valves, keepers and springs, rocker shafts and rocker box covers. All should be excellent candidates for OH but selling as is. I'm not a shop or A&P mechanic. $2400 for the set. Save shipping costs and meet me at OSH.
