Ron,
I would be very interested in what modifications you found to improve low end torque. Your book and JWL's book go into low end torque, but none of the other flathead books really cover the subject. Flathead engine books almost always are about making top end horsepower numbers and/or looking modified with lots of polished aluminum parts.
At this point my limited understanding is maximizing low end torque is all about more displacement (longer stroke since I want to keep the cylinder walls thick), higher compression, and a stock camshaft. With a stock intake and carburetor do you think there is any benefit to any port modifications?
