Obviously the flywheel, clutch and bell housing were destroyed also. If I didn't have a support cross member under the bellhousing, it would have been even worse. I would estimate I was out $4,000+ before I got everything back together.
Interestingly, the description in the NHRA rulebook specifying how to integrate an SFI approved bellhousing onto an engine where one is not commercially available for is based on my car, I actually wrote it up myself. At the time (1987), the rulebook said to wrap the stock cast bellhousing with 1/4" steel plate. I had made an adapter plate to mate a small block Ford Lakewood bellhousing to my 2.3 Ford motor which strangely was deemed illegal as it didn't conform to the rulebook. They did concede that what I did was considerably safer so asked me to write up the description so it could be included in the rulebook for future reference.

Thanks for posting. I did not know that.
I run a 2.3 Turbo Ford in Stk and SS so if I go to a manual trans setup it will have the whole slew of sfi clutch stuff
