67 Formula S

Looking at the 2 Barracudas I drug home. The K frames look different, although I believe both are for V8s.
68 looks normal to me

The 67 looks different in the oil pan area. More squared off. Maybe modified by someone.. The inner fender wells have been cut out , I assume for racing.

This isn't a Big Block K frame is it ?
