From BG Tech: "Most engines regardless of how radical the camshaft is don’t respond to increasing the timing (at idle) past about 18 or 20 degrees as far as idle quality"

First and foremost, I personally think that it is quite admirable to come onto the board to help "clear the air" a bit, especially with all the "HEAT"!

Interesting comment above, BTW exactly what we see with tuning engines that have well chosen parts and a carburetor capable of supplying plenty of fuel at idle speed and the engines vacuum level, REGARDLESS of how radical the camshaft has the engine running!!!

There are those on this board, who would ATTACK me viciously for making the same statement. It's commonly posted on here that a Pontiac engine "wants, needs, requires, has to have, responds well too, etc, etc.) to having 30, 40 or even 50 degrees of initial timing at idle (combinations of initial timing AND adding in more with a custom adjustable vacuum advance hooked to a manifold source)....and that using manifold vacuum to the advance is REQUIRED, not an option to a ported source.

We'll see if "they" swoop down and blast your comments as they always do to mine, if not, then it must be more "personal" than trying to provide usable accurate information instead?.......Cliff
