just wanted to see if anyone had any suggestion (or knew how to fix this). My 70 mustang has a 302 with an edelbrock intake, 4bbl holley, and MSD ignition. The car starts fine and drives great. However, whenever i hit 60mph on the freeway, the engine starts pinging. Also, as the car starts warming up, some smoke (white)begins to come out. Someone told me that i may have a vacuum leak on the intake and that i may need to replace the gaskets. Another person said that i may want to change the springs in the msd distributor to get a better timing curve. anyone know what it might be?
