Low Vacuum Issue/Big cam

I agree with the two people who said that cam is too big. Too much duration @ .050", especially for the lift. Yank it out, sell it and put in a Lunati Voodoo 268 cam. It's time people started realizing that MP is resting on it's 30 year old laurels with regard to cam design.

While you're at it, get rid of the Edelbrock carb and put a Holley 670 street avenger on it.
