Recommended Posts

Hi again. I have an opportunity to buy a Non A/C 1963 Riviera, once I sell my 1965 Skykark Convertible. 
 

Air Cleaner shows 445 Wildcat, but does that mean engine is the Optional 425(340 HP) or the Standard 401 Nailhead(325 HP)?

 

Cowl Tag is below.

There is much discussion regarding the “STAR” on GM Cowl Tags. There does not seem to be any rhyme to reason, as I recall....

 

Maybe someone else has more info on it.

The star means it was not made on a Monday or Friday😀
