JoelsBuicks Posted March 20, 2008 Share Posted March 20, 2008 I am having a difficult time finding standard size piston rings for my 1936 320 engine. The rings for later year's 320 engines are different but I do not know in what way. I've tried the vintage buick suppliers with no luck except that Bob's does have +0.020 rings. My max wear on the cylinders is 0.0065 with minimum wear at 0.0025 and so I was really wanting to just do a hone job and go back with standard rings. Does anyone have any suggestions? Can I buy the +0.020 set and file to get the right end gap? Can I get these made? Do you know what the difference is between the 36 320 and the later years? Thanks for your help!Joel Wilson Link to comment Share on other sites More sharing options...

JoelsBuicks Posted March 22, 2008 Author Share Posted March 22, 2008 Does anyone know what changed with the Buick 320 rings from 1936 to 1937? Joel Wilson Link to comment Share on other sites More sharing options...
JoelsBuicks Posted March 24, 2008 Author Share Posted March 24, 2008 I think I have found out the difference between 36 320 piston rings and 37-52. The 36 has 1/8" wide rings for the top two and 5/32" for the bottom two oil rings. The 37-52 has 3/32" rings for the top two and 3/16 for the oil rings. I've tried a couple other places that were mentioned and we'll see what they come up with this week. Thanks,Joel Wilson Link to comment Share on other sites More sharing options...
