And, the front bumper on my 74 was 62# with all the crash baloney. The rear was 82#, with said crash baloney.
The 73's, of course, only had the crash bumper baloney on the front.
(The crash bumpers were rated at 5 mph for the front, and 3 mph for the back, if I remember correctly. Any crash above those speeds, and the crash repair cost skyrocketed. Sigh, my hereos in government...)
I used fiberglass (hood, fenders and bumpers), so I don't know how the weight of 70-72 stuff compares.
At the old method of 100# = .1 second e.t., I probably picked up a solid tenth. Plus, most of the weight is off the front.
I built it with the fiberglass, so I don't have before and after e.t.'s.
I've taken this thread off track with weight mention, back to the op's question...
