Default Piston ring supplier found!!!

Total Seal of Arizona (623-587-7400) has the ring set I needed for my 432 V6. They have 301 rings left (minus mine). When they are gone, they might not make anymore. In case you are wondering, the complete set is $100 per cylinder. [Take Note: Total Seal provides rings by bore size primarily, thickness secondly and application lastly. Have your rings sizes ready just in case].

They provided for me a Moly 1st compression ring, a 2nd cast iron compression ring, an updated 3rd groove oil scrapper ring and a 4th groove dedicated oil control ring.

For my 432 CI motor that is 0.030 over, I gave them these numbers:

4.905" - 6 cylinder
3/32 x .225
3/32 x .225
3/32 x .225
3/16 x .200

These numbers came from Hasting Manufacturing. They used to make rings for us but no longer do. This is a lot of information, but I hope it helps.
