On P-14, the 7-11 Packer Pontiac is mentioned. The caption for the pic of that car explains how some of the big Pontiacs were shipped with a 348hp engine under the hood, but had lots of upgrade parts in the trunk, with which a guy could build his motor to run at 368hp.
They say that car was totaled in a towing accident, in '62, but not before scoring a class RU, at the '62 Nats, running 12.90's.
Apparently Packer sponsored several big Pontiacs back in the early '60's. Here's one with 7-16 on it. The 2nd pic is of a recreation of that car that was totaled.

The 3rd pic looks to be a recreation or rstoration of a later year model, with 7-11 on it. The 4th pic is of a silver '63 Cat. Don't know how accurate these cars are to a car that was actually raced. Also don't know if some are actually a restoration of the original race car.
This article says the silver "Swiss Cheese" car set a C/S nat record in '63, @ 12.27.
