Jeff,
There are a couple of guys on the Holley forum that will help you and also review your system. One of the guys has his own shop and knows his stuff and also races. Have you tuned it on a dyno? Also if you are not running an NTK O2 sensor that could be a source of poor performance. My standard O2 only lasted thru 2 dyno sessions and roughly 15 gallons of C16 when the motor fell on its face while testing. I already had an NTK and the motor came back to life.

There is a lot to be had with the timing and AFR tables, if your timing sync is not correct or stable thru the RPM range that may be another thing to look at.
