Hi Randy There is a little history behind this motor. I will tell you about it at Huntersiville. I will stick it in the All American Sr and we can have some fun with it. I also had never heard that they ran any better than the .35. When I was a kid I was told the "s" stood for speed not stunt! That is why I asked. See you at Huntersville. Eric V from Tampa Bay will be there also.He is my quest for the weekend.
