How to tell a Hi-Po original car from one that is not.

Question
What actually does determine a Hi-Po on the VIN of a Cyclone? Is it a K code like the Fairlanes or Mustangs, or is it totally different? (Doug)

Answer
As far as the HiPo car goes, there is no special vin code for one. They are all A codes just like a standard Cyclone. The only way you can verify having one is to have the original build sheet that is usually behind the instrument cluster or under one of the seats. At the bottom of the build sheet is usually something typed like "SUBSTITUTE 271/289 ENGINE PACKAGE". I have seen a couple of them and they all have some variation of this. I have the original paperwork that is from mine. Other differences are the export brace(see the picture underhood of my red car and you will notice it is a bolt in type instead of the welded in shock tower braces type on all the rest of the Comets and Falcons) It also has a unique 9" rear that has tapered axle tubes(very similar to the 65/66 Shelbys). There are other small differences like the exhaust pipe size, different driveshaft diameter and springs but only small stuff. (credit - Jerry Straight)
