1. HEI unit. ignition coil into the distributor cap, eliminating the need for a coil wire and adjusting them. HEI's produces both a hotter and fatter spark', huge HP gains.

2.2 barrel carb intake "more fuel flow"

3. go to pick and pull and get a new model exhaust manafold from a inline 6...maybe out of a truck of the 1980-85. they are 1/2" bigger....its like running a header..and run 2 1/2" mufflerand pipe.
