Engine builder got back in contact and confirmed 10.5 compression ratio and suggested 38 degrees on the timing. Initial is at 6 BTC.
Made the carburetor changes yesterday but was unable to take for a test drive. The changes were that I installed a 5.5 power valve and changed primary jets to #78's. Increased primary nozzle to #37 and secondary nozzle to #35. Not sure if the weather is going to cooperate today as we are bracing for some bad thunderstorms moving into Central Florida.

Don,
Do you have a vacuum gauge hooked up for bench tuning?
How are you data-logging your timing while driving?
Has the carb been rebuilt, or is it new out of the box?
I ask, as an engine under load will behave differently than an engine being tuned in the garage, at rest so to speak.
Finally, any chance you can get it on a chassis dyno for real world tuning purposes? I learned quite a bit after a good friend bought a chassis dyno and used one of my old Cobra replicas (427 sideoiler) as a benchmark for tuning of the car and different carb configurations (IE: 7 or 8 different carbs, and as you, power valves, jets, etc).
