"rare enough to warrant the switch back"....would it be "worth more"? to whom? are you selling it? or are you enjoying it....
if you could find a matching setup it "may" be worth more to a buyer...but if you enjoy it the way it is, just keep enjoying it...
personally I drive a "former" 350 car with 400 in it and 400 hood...non orig paint color and interior....just so you know where I`m coming from
