So I just finished building my 1940 JD B it was
bored out to 190 cubic inches with high
compression aluminum pistons. Its runnning on e-85
with an A carb and cold gas manifold and hot mag.
The head has been decked 20 thousands and has been
ported and polished. Can anyone give me an idea of
what kind of horsepower this will make. Ive read a
couple other posts that take cubic inches times
20% efficiency, is this a good place to start or
is that efficiency wrong? Also would you guys
recommend getting the cam ground?
