It is almost certainly due to rear axle location. Don is right.
It is a common problem as a very small amount of movement at the rear causes the car to steer all over the road.

Larry,
My TR8 used to do that same thing. I replaced all
the bushings in the REAR suspension (the ones that locate the axle) with
ureathane and it solved the issues. Under acceleration, the rear axle would
torque up and steer the car. It was effectively changing the wheelbase from one
side to the other with the stock softer bushings.
I am using delrin bushings on one end of each of
the four control arms on my Marcos, with ureathane on the axle end of the arms.
My theory is this should allow some compliance without being overly harsh
riding, while controlling axle torque.

Can anyone tell me what would cause the front end to be so squarelly on accellation?I have 3 cars here, and 2 of them, when power is applied, the front end wants to walk all over the road. All 3 cars have all new parts in the front suspension and new dampers all 4 corners. They all are total rebuilds and one car wants to wonder on the highway at all speeds. I have not tsken the third car on the road yet, so do not know how it will handle.Regards,
