[Rick 427 Cobra]

Check the motor mounts. The are l/r specfic and can be installed either way. The result will be an engine that is not parallel to the frame(out of phase!). Use a carpenters plumb bob and mark on the ground the edge of the frame on one side in 2 places. Then locate the centerline of the crank and output shaft at the front and back. check for parallel. The mounts should be installed with the stud forward and down (TRW mounts).
