427 Bellhousing and clutch fork

[coryh]

Was wondering if anyone could confirm if SA originally used a Ford bell housing and Ford clutch fork in their 427 builds and if so which combination.
There are many Ford clutch fork combinations but due to frame clearance issues I have read, unconfirmed, that the C4AZ-7515-A 12" clutch fork was used with the big input top loader.
The only bell housing ID I've come up with is the C5AA-6394-A that is listed for the 1965-67 427 manual transmission.
Thank you
Cory

I personally wouldn't use an oem Ford bell housing if I was going to beat on the car in any way. Granted, the old guys did. They didn't have possible Chinese rotating parts turning 7k rpms three inches from their knees?
