First, you have to sort the spark advance out. What distributor, what initial, does it have vacuum?
right now i have a stock hei with a msd 6al controlling it and it has no advance. when i git it i was told the driver ran it at 36* locked timing as of today i am running 32* it runs a little better. but im guessing a vacuum advance would be better? i checked my compression and 1 had 100psi across the oard +/- 2psi but it went to zero pretty quick (valve overlap?)like i said before i really dont know much about performance tuning.
