They are basically the same platform and only differ in W/B by 3 inches.

The 67 Mustang with a 390/320 hp is rated at 319 with iron heads and 327 with Edelbrocks and so is the 67 Fairlane with a 390/320hp, 319 with iron heads and 327 with Edelbrocks.

Mustang has 108" W/B, but the Fairlane has a 116" W/B. When considering HP changes per AHFS they are both averaged together.

I don't agree with that, but as long as it is the same.......

What about Mopars? They seem to adjust hp based on W/B. Just asking.....
