That probably isn't going to work. The 302 is a 2BBL NHRA rated at 143 HP. The weight break is 21.43 lb/HP but that will put you in U/SA at the 20 lb/HP category. In order to make the lower end of the class you would have to weigh 3030 lbs. It would be very hard to get a 72 Fastback that light.

It is interesting that the 302 had its HP refactored in August 2013. I don't know what it was previously or why it was changed. It was probably a competitor request to lower the HP, but maybe someone is actually running that combo. I have never seen one.

Keep in mind that there is virtually no difference between the 71 and 72 so you could run it as a 71 Fastback or Mach1 and look at those engine combinations too.

If you want to run it as a '71 429CJ/SCJ, let me know. I have everything you need.....
