will an OD unit take it

I had an aluminum cased OD out of a 76 van behind a built 383 in a 77 lil red clone with 3.91's and 3.23's. I had this truck when I was in high school...yeah I dumpped the hell outta that clutch...alot. It suprised me, I thought that it would just fall out of that truck and it held up with no problems.
