Gaz64 motor at idle is around 10" of vacuum at 1100rpm. Dana E. the cam is 254 262 @ .050, 609 609 with 104 intake centerline and 108 lobe seperation. Putting in the black bushing was an improvement over the blue bushing. I would think the larger bushings from 4secondflat would put me where my motor wants to be. Not going to lock out the dizzy....I think I can make this work. I'll order the bushings tomorrow and keep you posted.
