Help! Can't find file fit rings for .030 over 340.

[340doc]

I'm freshining up an old 340 build that's running the TRW replacement pistons with the stock 5/64 ring size. I've been on the phone with Summit and Mancini and they have no listing for the .035 ring. I found the old Sealed Power part number R10332+.035 but listed as not available. I'm scratching my head!

I wish those were the right ones. .030 over 340 is a 4.070 bore.

Sounds like you need to go to a piston with a more modern ring pack.

What end gaps are you trying to fit?

They're all file to fit when you use hypereutectic pistons. Lol

Use these... Hastings MS139070

I doubt if he is running dinosaur rings in his stuff.
But who knows

Speed Pro used to make a set of plasma moly rings .030 file fit for those pistons. I have not bought any for years.

That's what I used to always use. Apparently not available any more.

Thanks to all who offered help. Hopefully found them at Total Seal like some suggested.. Not in stock but should arrive end of the month. We'll see!
