'1967 Holiday Race' ~ Plymouth GTX 440 vs. Pontiac GTO 400 'Ram Air'
1967 Plymouth GTX 440/375 HP 'Super Commando'
vs.
1967 Pontiac GTO 400/360 HP 'Ram Air'
Stock vs. Stock ........... 4-Speed vs. 4-Speed
Have to go with 'The Goat' here, by a solid win.
Remember, the GTX was equipped with 3.54 Gears in the Dana Rear. Though, thru a
'Special Order Only', you could finagle 4.10 Gears.
The Pontiac GTO came thru with 4.33 Gears {as standard equipment}.
The GTO also had the advantage of an M-21 {Close-Ratio} Transmission.
* M-21 ....... 2.20 ~ 1.64 ~ 1.28 ~ 1.00
* A-833 ...... 2.65 ~ 1.93 ~ 1.39 ~ 1.00
And, the GTO came equipped with a Hurst Shifter, while the GTX was equipped with
the 'junk-link' Inland Shifter.
The GTO also had an advantage in Tire Width, with F70 x 14"s {6.55" Width}. versus
the GTX with 7.75 x 14"s {5.50" Width}.
But the 'baggage' was the real culprit here. In 'Curb Weight', the GTX was heavier
by {+267 lbs.}. That is a lot of 'Meat'.
