Re: [Chrysler300] How did the 300 B turn 139 MPH at Daytona

["Owen & Jo Grigg" <ram300@xxxx>]

The racing & speed trials run at Daytona Speed Week were sanctioned by the
AMA(Auto Manf Association) so the cars had to be as they left the factory. I
have a '57 Daytona video where they show the cylinder heads being pulled to
bits prior to racing by officials. They were checking for any port work,
valve sizes etc etc. Everything had to be stock. The engines were then
reasembled and tag seals put on all components by race officials so there
was no "tweaking" after the inspection.
These things ran close to 140 out the factory door!

Does anyone have knowledge on what was done to the several 300 B's that ran
at Daytona in 1956 that ran up to 139 mph.
How close to stock were they. Somehow I have a tough time believing that
running on sand with the aerodynamics of a sail turning upward of 140 mph
with a stock motor would be doable.
