idle problem with long duration cam

What are the rest of the specs on the motor? Did you ever take a cranking compression test on it before? 950 is a little high, which is why it pulls on the convertor. Also, what is your full timing curve? not just total, but initial and centrifical? Im assuming the vaccum advnace is already not in use. What about power valves and/or idle mix screws? When was the carb last rebuilt?
