I wonder if your supercharger is giving any boost,There are some poor superchargers out there.Has your car always run this badly?
Do you have any photo's of the engine bay?
I've never tried this but if the blow off valve is accessable you could try taking it out and either hold your hand over the hole or a suitable plug and start the car,under throttle the supercharger pressure should want to blow your hand/or plug out if you dare to try it!
Unless you have a boost gauge that is.
Don Rawson knew how to build a good seven engine so originally it would have performed well.
