I have a 37 Chevy truck that I am just starting on. I have a 350 260hp crate motor with an Edelbrock intake and carb with about 30,000 miles on it. I also have a never fired rebuilt 1972 292 Chevy inline 6 bored .30 over, but basically stock. What is the difference in weight? Also does anyone know how much horsepower and and torque the 292 made in 1972?
