Holley carb jetting 101

Is it rich just at idle and or on the road?

For on the road, your specs look OK. You wouldn't want bigger jets if it's already rich on the road.

At idle, your mixture screws should both be out about 1 1/8 to 1 1/4 turns, then increase the idle speed until it smoothens out. (For auto and manual brakes around 825 to 850 rpm for your combo.)

Holleys are wet flow tested before they are boxed. The jets are last thing I would change.

Maybe a vacuum leak??? thereby adding more fuel to compensate for rough idle?

Actually I misspoke, the idle in park is not bad (I adjusted both idle mixture screws 3/4 turn leaner than it came out of the box) It idles ok... just not as smooth as I would expect with that mild of a cam. When I punch the gas in park it does hesitate just a little bit.

I was actually thinking that the jets I have now are too large. Before I go changing jets I will check the vacuum pressure first 8)
