It as the '70 Falcon that had the odd 8-bolt valve body. All others apparently had the standard '70-'73 9-bolt type. If yours uses 9 bolts to hold the VB on, you can use the standard shift kits and stuff. The 26x26 input is not an issue if you don't have to replace the forwrd drum or want to install an aftermarket input shaft over 600ish HP. In either of those cases, you would likely change to the '71-up 26x24 input and drum as a pair. Otherwise it's a good base to build on.
