Nothing to be ashamed of here! It's still a cool '70 Challenger! Hope you're not too let down. Sorry if you are.
Like Barry said, it'll handle better and plus you'll be cruising by the big blocks at the gas pump!
I dunno, if you already have the R/T emblems, why waste 'em! Toss them on and give it an R/T look, sort of along the lines of the A66 package!
Go for it!
