Yes. There were about 3,000 of them made between '69 and '70. It was an ultra-high performance model used for homologation into
Trans-Am. You'd be better off buying a '69-'70 SportsRoof, a new Boss 302 block from Ford Racing, and a Clevor kit from Edelbrock. (p/n 2059, I believe. bottom of the "Ford Top End Kits" page). And with that, you also have the freedom to install whatever transmission, suspension, whathaveyou, without purists tearing you a new one. I know this because I plan on doing this build when I get out of college. It'll probably end up being about $40,000 for my build.
