Help with fender tag decoding

[histoy]

I'm looking at a '73 Road Runner.  I've never owned a Mopar this new, so I'm not familiar with the codes on the fender tag.  The engine code is E68 and the paint code is FE5.   Could someone let me know what they are?   Thanks in advance for your help....Brian

E68 is a 400-4bbl high performance

FE5 is Bright Red paint

Thanks for your help.   The car is red and has a 400 engine.  Not sure at this time whether it's numbers matching.
