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.




Correct 1972 Road Runner Engine options are 340 400 & 440+6BBL

U code = RR / GTX Engine 440 4BBL.

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.




See I never looked at it that way. To me 72 Roadrunners were available with the 400 standard and the 340 440 4 bbl and 440 6 bbl were optional. If you ordered the 440 you got GTX emblems. Since they are all RM code they are all roadrunners. Just some got Some emblems. There was no seperate code for it. I seem to remember factory paperwork that says that all 440's got GTX Emblems I am going to look for that tomorrow at work

As far as 4 speed you could not get a 440 6 bbl in 72 with a 4 speed that is part of the paperwork also.

Here is the paperwork on 440's becoming RR/GTX.
