I have a 9 year project of an '85 Shelby charger that I have built primarily as an autocross car. Last year was the first year out with it and I only made three or four races. I'm still sorting out bugs. I noticed a rubbing on hard left turns which I assumed was a tire. After it developed a power steering leak, I realized the rubbing was actually the engine shifting enough for the power steering pully to hit the frame. At rest there is only about 1/4 inch of clearance between the pully and the frame. I never remembered it being that tight. I used stock rubber mounts and filled the voids with window weld because it does see some street duty. Have any of you encountered this, and short of urethane mounts what can I do?
