Match Race 1972 ~ 'Road Runner/GTX 440' vs. 'Buick GS 455'

1972 Mopar 440 'trick'.

To squeeze another 3/10's off the Elapsed Time.

Mopar made a lighter spring kit for the Distributor Advance {P/N 2084301},
as well as a different Cam and Stop-Plate for the Distributor internals.

Set the initial advance to 15* {at Idle}, and 35* Total {at Full Advance}

And on the Holley Carburetor, enlarge both the Primary and Secondary Jets,
one size.

It made a 'World of Difference'.
