'63 was the year of the "Swiss Cheese" 421SD Pontiacs. Weren't enuff made to be legal in the lower Stock classes. But, they could run in the upper FX classes. I think the B/FX final @ Indy was between 2 '63 421SD Pontiacs. Jim Wangers drove the winner.

Arlen Vanke drove one in A/FX.

There were several 421SD '63 Tempests built. IIRC, Pontiac built & shipped 8 of 'em, 2 of which were wagons. The quickest were those which had the stock Tempest type rear driveline replaced with with a Pontiac chunk type rear end like those that came in the big Pontiacs. They were much stronger & more reliable.

The M/T 421SD '63 Tempest that won A/FX @ the Winters was driven by Bill Shrewsberry.

Jess Tyree eventually had one of these Tempests.

Arnie Beswick eventually had a '63 Tempest, Tempest wagon, & a big Cat, all with 421SD power. Ran several different classes with 'em.

Don Gay eventually ran one of the wagons, for a while, along with his '62 421SD A/S Cat.

Right now, I can't remember if I've seen a class winners list for the '63 nat events, or not. So, the above mentioned wins are all I can list, for now. If I come up with more, I'll edit & add it.

Here's the video of part of the '63 Indy nats. Between the 2:00 & 3:30 points of the video, are the A/S & A/SA class finals.



The 1st part of this video also shows glimpses of some Pontiacs @ Indy '63.
