I was in Tijuana several years ago, and I saw a '68 or '69 station wagon with 428 fender badges that was being used by a street vendor to sell food out of. It had a big fat "$" on the windshield that means "This car is for sale, please inquire about the price and depending on who you are will determine the price". I talked with the owner for a bit trying to act like I just needed a good wagon, then I asked if I could peek under the hood. When I opened it, it had a 302 in it.
He said I could have it for $500. I assume it was an original 428 car that had the 302 slapped in at some point. I doubt this guy added the 428 fender badges to make it look racy.
