What piston are you using? cylinder head? 292 cam will need some compression.
Gonna need some low end torque to get 3500lbs moving.

Question #2-
What’s the budget for just the engine(carb to pan), and what parts do you already have that you plan on using?
You must have some idea of a budget and a basic idea of what parts you're using, an answer would be nice.
