OK- - - -it looks like you've got the torque problem addressed, if not completely solved. Do you plan to do any dyno work before you assemble things? I'd be looking for a very flat torque curve, one that will avoid having to downshift frequently. With a Brownie and a 2-speed axle, you'll have a good variety of ratios to choose from, and probably even a few selections that won't be needed if you make good choices of camshaft and ignition timing.
Do you have a crankshaft grinder yet? I might be able to help out on that subject, but that conversation would be better by PM.

Jerry,
The only dyno I have close to me is a chassis dyno (It's actually just across the street from me). I would prefer an engine dyno, but anything would be helpful to know what's up. I'm told the engine will make more torque than horsepower. The cam choice will cause the engine to start to fall off at around 5,200 RPM, and the sweet spot for towing up a steep grade under heavy load to be somewhere around 3,600 to 3,800 RPM. Conservative estimates are 500 max HP at 5,100 ish RPM, and 550 foot pounds of torque at 3,800 ish RPM. I'm also told to expect at least 450 foot pounds of torque at about 2,000 RPM. We will see. The EFI will help me extract more power from this engine more safely. Being able to electronically detect detonation and control spark advance prevents damage under less than ideal conditions.
I will read your PM.
Thanks,
David
