carb issues

[PKRWUD]

Holley knows their stuff, believe me. They tend to tune for the average car, though. You seem to be losing power at the end of your run, which is often because the PV closes too soon. I'm not guaranteeing the 8.5 PV will be a miracle cure, but it should be better. If it's too much, you'll run extremely rich at idle.

Ryan-
Sorry about causing you to lose traction.

The cams all act differently, and in all the Holley books I've ever read, none of them recommended the green cam, but it's still my favorite. And now you know why. Books are great, but experience is invaluable.

Your vacuum numbers sound better than they did before (8" at idle couldn't be correct if the mixture and timing were on), and by answering my hypothetical question, I can say with confidence that you don't have a vacuum leak (if you did, the engine would stall during a panic breaking condition).

Now that you have the single best tool for working on engines, use it to adjust your idle mixture, and make sure you're on the money. As far as your vibration, I'm thinking you should be looking at your tranny/convertor.
