318 to a 360 motor mounts

as long as the car was a v8 originally youll be fine. one side bolts on to the frame and the other lowers into a groove. if it had a /6 in it well theres a kit for that

my car was also a manual trans, and with the auto setup everything still worked fine. hardest part was getting the dam starter in there around long tube headers. correct me if im wrong but you want to bolt up the starter before droppin it in?
