Marquette Flyer 1 Posted December 20, 2018 (edited) Looking for piston rings. The bore size is 3 1/8, there must be other engines that used this size pistons. From what I've learned the block is Oldsmobile. While tearing this engine down I found the connecting rods are Buick. If anyone has a set of rings or happens to have an interchange book could let me know what other makes may fit. Edited December 20, 2018 by Marquette Flyer Add more description.

Marquette Flyer 1 Posted December 29, 2018 Thank you sir! I did find this set, has the same bore size, I have to check the ring groove specs. It doesn't list the Marquette, then again... not many do. Share this post Link to post Share on other sites

Marquette Flyer 1 Posted December 29, 2018 I'll give them a shot, I called Hagens who wanted $150 for a set. There has to be cheaper out there. Share this post Link to post Share on other sites
