one of two: you people just suck, or these are not quite as popular and well-known as I thought they would be. It must be the first option.
Yes they were a racing-intended model
@Custom878, the A-864 Savoys were part of Mopar's factory Super Stock efforts, the other being their Dodge A330 counterparts.
In the case of the Plymouth, yes, the grille had only one headlamp to save weight
@playnthru and they were not produced like that, they were actually hacked together from two stock grilles, as these were cars not intended for public use and thus, they did not comply with Chrysler's normal warranty. Of course, these were not the only weight-saving tricks, they had aluminum front fenders, hood and bumpers, Dodge van seats, and in the case of the Hemi cars, aluminum doors.
Which leads me to what
@Slash was saying. Yes, there were A-864 Hemi cars, but those were the last of the run of... er, I think 120 or so that were made, as the race Hemi engine was launched in '64 and the cars that got them were built in the latter part of the year. The early cars had Max Wedge 426 engines with cross-ram aluminum intakes.
I'll keep my internerd.
