We set the HEI at 36 degrees total advance and made sure fuel flow was at a steady 6 psi. The dyno pulls we made with each carb showed promising results across the board. Although peak power figures were slightly lower than what Edelbrock's 383 made, our engine was almost 30 ci smaller, so we knew we had a winner here. The same set of 1 3/4-inch headers were used in all tests. 1 5/8-inch headers may have made a little more torque, but we didn't have a set to try out.
