Please show math..
I get ~ 4.1 ci
That is what I was trying to say, it has a bit to much displacement for the 4 cube class, and not enough for the 5. I ain't smart enough to do math, but know the 372 is 50x36, and 72cc.
The 70 may also have a 35mm stroke on paper, but I get 34mm measured with the crank chucked in the lathe.

Too bad it's gotta run against those blasted 372's...
I like it's chances against an 044 though.
