Re: Superbirds/Daytona Chargers is statement true
[ QUOTE ]
If you spot a 70 Road Runner with a "U" engine code (I.E. RM23U0), it's a 'Bird. [/ QUOTE ] For the uninitiated, that's because the Roadrunner came with the 383 (N code) or the 440-6 barrel (V code) or the Hemi (R code). Only the GTX and the Superbird came with the 440 4bbl (U code) in 1970.

Re: Superbirds/Daytona Chargers is statement true
Steve, do you mean to say just in the B bodies? I have owned 2 E bodies (cudas) with the "U" code 440 ci 4 barrel.

The "U" code engine is the standard engine for a S-Bird but it was available optionally with both the six barrel and the Hemi as well.

One lucky guy over here found out that it wasn't just an ordinary Hemi roadrunner he had, it was a Superbird. Telltale was of course the rearwindow and the rearwing reinforcements in the rear quarters. Car is in its final moments of restoration and should be ready for next summer. Jan

Re: Superbirds/Daytona Chargers is statement true
You're reading way too much into this. He was just giving a heads up for people. What he is saying is that since the 440 4bbl was not avail in a RM23 Roadrunner, if you find an RM23 Roadrunner with a U engine code in the VIN, it was originally a Superbird because there were no 440 4bbl Roadrunners except for the RM23U Roadrunner Superbirds.
Your buddy's car must have been a heck of a find. Not only a Superbird but a hemi, too. Was it found over there or in the states and shipped over?
