hi, i have a 67 malibu, and came with a 350/2speed pg. i have just noticed that the steering(don't know the correct term) is rubbing on the exaust manifold. its rubbing pretty good cause its really worn down. could this be caused from having the wrong monifold on there. I am planning on putting in a 396 sometime next year and would this cause even more problems? has anyone had this problem before?
