Which one was quickest in 1972

1972 Plymouth Road Runner/GTX

'U-Code' ... 440/290 HP ~ 4-Speed

Only '219' 4-Speeds built.

Dana Rear w/3.54 Gears was 'standard only'.

But, 4.10's could be installed, providing it was approved by the Regional Office only.

Not any 'Joe Buyer' could get the 4.10's. You had to have connections at the Regional Zone Office,
or the Dealership had to be Performance oriented with a 'well connected' Sales Manager with pull
to get the Code A-34 'Super Track Pak'

The Newark, New Jersey {Northeast Region Zone Office} had about a dozen requests for the Special Order
'4.10' Gear Package.

We tested one with 4.10's for Super Stock & Drag Illustrated at New York National Speedway, and the
Road Runner/GTX ran in the mid 13.80's @ 102 MPH.
