This sled is a perfect example of a completely original modified grass drag racer circa 1971. It had started life as a 1970 Sno Jet GT-2 396, and in 1971 was modified for grass racing. The only stock GT items are the chassis (though heavily modified), and the bottom end of the motor. Here are the specifications:

This machine was originally a 1970 GT 2 modified back in the day for grass racing. Was located in Ionia, Michigan in 1996. There is a strong possibility that this was one of Jim Adema's the process of researching it's provenance. It is a rare survivor nonetheless.
