I’m doing exactly that to my 73. Everything will ‘look’ 1970 including the T/A theme, so a ‘70 T/A Tribute’ it is......or will be. Mine will have a little ‘pro-touring’ in it too, which is a personal like for me. But that’s me.
Not sure if your value would be much higher, but possibly, since the 70-71 is MUCH more desirable than 72-74. So, based on that, it’s possibly a ‘bit’ more valuable than being a basic 72 or 73 or 74. I would say, having a 440 6-Pack & 4-Speed certainly helps!
I have my 572 aluminum hemi built by Tim Banning @ ‘FHO Hemis’ which adds to value, plus I’m converting to a Hilborn 8-stack EFI injection, which I hope would increase value as well. Soooo, I truly hope my 73 will be worth more in the end, BUT Lord knows how much more!
ASK yourself,.....if you have the money, could you ‘build’ one for the same price as the one you’re considering buying?? I’d hate to tell you how much I have in mine!!
‘BUCKEYE CUDA’ said it’s worth ‘what someone’s willing to pay’. That’s pretty accurate! Not sure where you go from there.
