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

Before I post the Buick GS Stage 1 'specs'.

In 1972, Plymouth discontinued the GTX Model.

You had to purchase a Road Runner, with the 'GTX option' to get the 440 'U-Code'
Engine.

The Code E86 '440 Package' was only $161.

For only an additional $67, you could add the Code N96 'Fresh Air Package' that came
with the 'Air Grabber' Pop-Up scoop.

This came with the complete under-hood Cold-Air Induction System.
* Special Hood
* Plastic under-hood air box
* Special lower Air-Cleaner base
* 'Coyote Duster' Air Cleaner lid
* Hood Scoop system with vacuum actuated control
* Hood Decal

And, the 'specially-calibrated' Holley H-4-4160 Series 670 CFM Carburetor.

Though not advertised, the 'Fresh Air Package' was worth an additional 10 Horsepower
