My first concept was a '27 tracknose with Duval split style windshield. Pic on the left at this site.

For driveline on the '27 I would look at the HPGC 50 atached to a shorty Powerglide. Owners thread here.

Fill the nose with batteries and Electronics. I would bet you could come in under 1500 lbs if you keep it simple.
I wanted fenders for better foul weather and aerodynamics. So I am patterning my body of a sectioned and chopped '37 with the Duval split style windshield and removeable hardtop(or perhaps woody!). I am shooting for under 48" and under 2500 pounds.
