Maybe this will wake everyone up about isolating.

My 367, in a different iteration, has done better than 25mpgUS, point to point, and that combo went 12.9/106 on it's only time at the track. And it burned 87E10 100% of the time.
I could tell you that, that engine also made over 30mpgUS, point to point, but people say that is impossible.
I could tell you how I did it, but that's another book.
I know you guys are poking fun at me, and that's ok,no offense taken.
