Mexican Super Bee

Whats the recipe for the 318 used in the Mexican Super Bee's.....how did they get the 270HP rating. I am aware that they used the 360 later on but I am interested in the 318 for now. I am becoming more and more interested in these cars both A and F body variants...very cool cars! Thanks
I wonder it Mex. used net or gross hp rating???

I bet the F bodies groups in FB can tell you if no one here can. There are a couple guys there that know everythng about the F body.
