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

This surprises me a little, but there's probably 50lbs in the Dana over the 10 bolt. And I wouldn't be surprised at all if the majority of Buicks had A/C on top of it.....At least most that I've seen at shows or in magazines have.

O-M-R

That is the 'base weight' of the Road Runner.

With the Code E86 'GTX Drivetrain Option' and the 440 Engine, probably added a good +100 lbs.

The Buick GS 455.
Add +47 lbs. with the Automatic Transmission
Add +93 lbs. with the Air Conditioning System
