Re: TRW/RAMCO Piston Rings ???
John, couldn't find that # in my TRW cat#RC-283, dated 1983. Probably because it's a "Performance Components" catalog. Closest number was T8327M, single moly set for 6cyl with 3.50 inch bore.Sorry.
You could try slipping them into a tapered ring compressor for a 350 and see what the gap looks like.
