FOUND! - WTB - .020 over cast iron piston ring set (1965 110hp)
Posted by: Paulsgt ()

Good day!
This may be a long shot but both vendors I spoke with today either don't carry or are out of stock. I am in need of a complete set of .020 cast iron piston rings for my '65 110hp engine. Anyone have a set they are willing to part with?

Thanks very much!

Enjoy the Corvair!

Hastings are pretty good rings. I have had poor results with Grant rings twice. Bad quality

Very hard to find.
Given the large .020"or bigger gap of most new Corvair ring sets , you might try a single .030 over bore CAST Iron ring and see if it can be filed to a.012"- 014"end gap.
This is the correct range for a Corvair ring end gap.
I have done this in the past In a pinch.
I did use a 220 hone to help the ring break in easily.
This will not work with Chrome edge rings!!
One time , many years ago I even used a lightly used .030" 0verbore ring set to do this.
For a " Econo " street engine rebuilt
Turns out not much filing was needed.

Obviously, the end gap needs to be measured 1/2 way down the bore with the ring squared up with a inverted piston.
Due to the natural taper wear in a Corvair cylinder, if a used cylinder is being used.

Bump.
Although my need is not yet immediate, I am still looking. All online vendors and Clark's are out of stock. Does ANYONE have a box sitting that they don't need?

Thanks very much!

Enjoy the Corvair!

I don't have any new rings around to measure. Can someone answer Mike's question? Thanks very much!

I got scammed on this request but all they got from me was my email address and what city I live in. The scammer was deleted from the forum.

Enjoy the Corvair!

The DAY after I was scammed (didn't loose any money) it popped up on two auto parts sites I was monitoring that they could now supply the LM Corvair .020 piston rings. I placed an order with Summit Racing. According to my email today, they will be delivered tomorrow. I'll keep you posted.

Enjoy the Corvair!

(1) Set of LM Corvair piston rings .020 over sized by Hastings (Made in USA) showed up on my doorstep today. I really don't use Summit Racing very often but they were the first to update their inventory with availability.
Just got a call that my crank and block are ready! Now just waiting for the heads to be finished.

Case closed.

Enjoy the Corvair.
