Vacuum Secondary Issues
I just installed a brand new Holley 80531 850 vacuum secondary on the car. The issue I'm having is that the secondary's aren't opening soon enough (5500rpm) and I have the lightest spring installed (Yellow/Short). It's not a smooth transition either. [img]<<GRAEMLIN_URL>>/mad.gif[/img]
I do have the check ball installed which is highly recommended by Holley. I am using a thin 4 hole aluminum spacer plate under the carb with my Edelbrock TM2R intake. Thanks, Kurt P.S......the initial feeling is that the motor REALLY likes the 850 vs. 780. Only the track will tell! [img]<<GRAEMLIN_URL>>/naughty.gif[/img]
