Crank Case Stuffers 73 Polaris TX Starfire 295 340 439 Vintage Snowmobile Lot 4

Description

Don't remember where I got these from, but they came in a Polaris inventory. They have been in an engine. They fit both the 72 and 73 Starfire case very well, but they don't fit inside of 72 pistons. They do fit well inside of 73, 295 & 439 Starfire pistons. The 71 case has a lot deeper transfer passages. The idea behind these was to reduce the crankcase volume to make more power. Don't think they did much, but they are a cool piece of snowmobile racing history. They were screwed and epoxied into the case to hold them in place. This is for a lot of 4 of them. As is
