The Jett .35 doesn't hold a candle to the Nelson .36 Combat Special though. Not even debatable, it was painful to watch the Jett .35 try to run against the Fox and Nelsons. A couple guys tried the Jett.35 and it didn't even measure up to the bone stock $80 Fox Mark 3, 4, or 6 engine.
My OS .32 made a better showing than any Jett .35s that I've seen.
If you are looking for the most bang for your ".35 sized buck" the Nelson .36 is still miles ahead of the rest.
Like when rating the heat of chili peppers there is a group that are pretty hot, but then you see habaneros rated in a seperate universe.
If you see a Jett .35 running with nothing else to compare it to it might seem impressive but there is a good reason why this engine never won even a 7/11 burrito at any fast combat contests in the USA.
