Thanks for the replies. My balancer has not slipped. On the dyno it made the most power at 39 degrees total. I checked the stats, and the initial is 18 and the mechanical is at 21. Again, I am running full time vacuum advance of 16 degrees all in at idle. I already am on the threshold of running too much initial as any more seems to become a problem for the starter.
The mixture screws are very responsive and are set about 5/8-3/4 turns out. That seems to be maximum vacuum (11 +/-) and rpm. I have the idle set at about 950-975.
Again, the car runs great, I just am so thrilled about the cold responsiveness that the letdown when warmed up is frustrating. If I had not ever experienced how crisp it is cold, I probably would not think anything of it. I just know that if it can be that crisp when it is cold, I should be able to get it that way when warm.
Could it be a manifold that is too warm? Perhaps open crossovers causing excess heat from the exhaust?
Thanks again!
