Car is ladder bar rear, was tubbed etc some 6 years ago and has run perfectly, arrow straight and without drama.. Runs mid nines on the gas and tens on motor..over the last winter I changed the Camshaft and also replaced the rear tires, mickey Thomson street radial, now the car cannot hook up off the line and down track it tries to move around very badly.. I have a Detroit locker in the rear end.. Is it possible the locker could be causing this, because everything under the back of the car looks exactly like it did last year... When driving on the road, if I blip the throttle the car feels like it jumps to the right and when I come of the throttle it seems to jump to the left
