I like your car.
My 73 might be slightly lighter than your 72 (I've lightened it a lot, but it still has steel bumpers and stock doors and glass. It weighs 3510 with me in it. It has a little less compression than yours (11.4), and a little less cam (.585 Ultradyne flat tappet)
It runs approximately the same as yours:

7.32 1/8
11.45 1/4
1.55 60 ft.

I think mine might 60 ft better because I have 10.5 x 29.5 slicks.
