Part 4 some part swaps. New Spintech mufflers and a big Thanks to Ron at spintech for recommending them and getting them built so quickly. Great tone with enough reduction in volume to make the car more enjoyable around town. I also took the 600 double pumper off and installed a Holley 80770 Street Avenger 770cfm carb and what a difference that made, now the car responds really well. I also installed an aluminum radiator since the car was trying to run at 200 degrees with our cooler weather I knew summer would be brutal. The new radiator has cooled things down by a good 20 degrees. I picked up a Mallory Hyfire IV ignition box and increased the jet size in the primary and secondary and the car just keeps getting better.
