I am looking for a part number for piston rings for a 1945 ul Flathead. The rings that are currently in are way out of specs and need to be replaced. Thanks for the help
depending on overbore, and top compression ring thickness, see groups with 430-452 or 433-208 in them
For my 2nd ring, I use Total Seal Gapless rings on my Flatty stroker..
Helps with blow-by, but more Importantly it helps draw oil up the cylinders (an Important thing in any Flathead)...
