I know how to set the idle mixture thanks Nick....I'm more prone to go with the too tight torque converter theory, as the symptoms really agree. The tranny is a stock BB push button with an unknown converter. The cars slams into gear and jumps from the higher unloaded idle RPM and then barely lopes along in gear. I'll get some actual numbers on idle speeds and vacuum later today. I agree this cam doesn't seem this big and should be able to work....But I haven't to make it so in 10 years of messin with this. Yes this car has ran this way for a long time.
