Hi again Matt
I forgot to share that the day the original owner took Possession of our 78 Royale (we are the second owner) he had the 403 taken out and a professionally built turbo charged 455 put in its place. Ran all Over the west like a scalded assed ape pulling a horse trailer to his daughters horse shows with the factory 307 final drive. Lasted 42,000 miles. We purchased it after a naturally aspirated 455 was built to replace the burned up turbo unit. We later changed the gearing to
370 and found that just right for the way we drive.
