TRW/RAMCO Piston Rings ???
 

Would anyone have an old TRW catalog laying around ??
I was going thru my junk and found a box of TRW/Ramco piston rings T8325M and haven't a real clue what they are for ! I think they might be for a 350 Chevy....I just don't remember.... Any help would be appreciated. ..JLK

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.

John you have a PM

AH HA! TRW cat.#E-178 77-78 Pontiac 301. I thought it sounded familiar. Thanks, I needed a brain tease this morning. It's a 4" bore so I guess that you could put them in a 350 , thickness is the same but I don't know about depth.

John,
My 86 catalog shows it for a 350 Chevy.

Re: TRW/RAMCO Piston Rings ???
 

T8325m can definetly be used in 4.00" bore based Small Block Chevy.

THANKS EVERYONE !!!
It just so happens I have a standard bore 350 up the hill that's been setting for about 5 years that will need new rings !! Now to get a set of decent heads and I can put it in my '72 Chevelle that's been setting unused for quite awhile !! :-)
