John and 1fastredsc,

According to both BA and Wayne's books, early SCs had 39mm intake ports, late had 34mm.

I don't have an SC nor any car with CIS, nor have I been able to find someone who will try to rig up a test, so there is no way to check my suspicion.
What do you have in mind for rigging up a test? I may be game.

If you have a vacuum guage, you can try it by hooking it up with a T connection to an existing vacuum port to the manifold or plenum. Take it out for a drive and run it up to redline a few times and see if any vacuum is detected.
John, not sure what you mean here. I know late SCs pulled a vac under load, the vac advance for the distributor. only works with the throttle open. Or am I misunderstanding you?

Has anyone ever punched 3.0 numbers into dyno software? I am trying to figure out a strange torque curve and would like to do a virtual port job to see if anything changes.

Do you need to be an engineer to understand it?

Tom
