how to i.d. a 4 speed bellhousing

How can i tell what my bellhousing is out of , such as v-8, six cylinder? Is there a number stamped somewhere I can reference to? My car is a 65 barracuda with 318 4-speed. I am having problems with the z-bar fitting properly Also would like to know if the forks are different from 6 to v-8. The guy I bought car from was a real cobbler and I would to get it back to stock.
Thanks, Stoke
