Ronnie Sox 'Performance Tests'

1967 GTX 440,

A 4-Speed with a {Code #408} Dana Rear and 3.54 Gears.

Before Sox & Martin got their new 67' GTX 440, that they would run in SS/E
in 1967.

In October 1966, they tested a new GTX in Detroit.

* Shipping Weight......... #3535 lbs.
* Curb Weight.............. #3765 lbs.

The 'best' Plymouth Techs were running 14.30's @ 98 MPH in a 'stock' 4-Speed,
with 3.54 Gears. Of course with a 'mild' performance tune-up, and the GTX equipped
with 14" Magnum 500 Road-Wheels on 7.75" Red-Streak Tires.

Ronnie came in, and had them pop on a set of 15" x 6.0" 'JK' wheels from a Chrysler Imperial,
with 9.15 x 15" Tires {29.60 Tall x 5.40 Width}, and then swapped in a set of 'colder' Champion Spark Plugs.

A few timing adjustments and tweaks on the Carter AFB {750 CFM}.

The GTX had a 'new' pair of shoes...........as Ronnie averaged 14.04 @ 102.1 MPH after 7-Runs.

With a best of 13.98 @ 102.3 MPH.

That's with an 'Inland Shifter'......................
