SCOBRAC is right, after pulling, changing, re-install and driving about three times.
I found the best performance with my high overlap cam (7 inches @ idle) and dual 600's was to..... change jets to 64's, drill a 3/32 hole in each throttle plate for better adjustment, install the short yellow springs, remove choke assy., recurved dist., initial timing 18 and 38 total. Acceleration is unbelievable.
