On the factory distributor for the 292 L6 Does anyone know what the curve is by what RPM is all the mechanical advance in?

Same question for the 6 cyl HEI Ignition?

Has anyone had any luck fabricating a throttle linkage for the Holley Weber Carbs?

Application is a 64chevy P/U 292L6 converting from a Rochester Monojet to a Holley Weber.
I have a Carburetor adaptor From Stovebolt Engine Co. Mfg by Trans Dapt #2025 to mount the carb to the intake but the linkage on the H/W Pulls Clockwise while the Rochester pushes Counteclockwise.
