The car has some pull to the right under acceleration and then darts left when I lift. The car is a 2500 super gas strut front end and four link rear. The front end was just lined up so I'm thinking maybe something in rear. Nothing appears to be broken or bent. This is a new car to me.
Have you checked the chassis square ?
Is the rear end square with the chassis/front axle line ?
Sounds like it could be the right side wheelbase is a tad longer than the left.

Lets start from scratch. You said the car was new to you. Did someone have it before you or did you build it? If someone else had it did it drive straight? What have you done to it since you've had it?
May sound crazy, but if something changes always think back to where the problem started.
had a super gas camaro doing simular thing....finally got to the point where it was swaying all the way down the track. Tore all the rear end suspension apart and found panhard tube bending under load and all heim ends were .002-.004 loose. replaced all ends and converted panhard rod into the newer style x-link setup and was fine after that.
