Quote: I think he meant that the 440 4 bbl was not offered in the 72 rr and if you had one it was a gtx option on the 72 rr. The 340 and the 400 were both equipped with the 4 bbl. The Petty blue 72 rr that was on ebay had to be the gtx option as it had the 440, but he said i was a very rare rr. I am not sure if the gtx option in 72 was a code on the fender tag like the rr option on the volare but would make sense to be coded like that.
This has nothing to do with WIW. Larry at this moment you have the only example we can use as a reference. I want to thank you for answering these questions. I am very into the research of the 1972 V-Code Road Runners.
