bench race

I looked at pontiac's numbers when I got to work today. A 73 SD was rated at 310hp, 8.4:1CR. Standard 455 was even 8:1CR and rated at 250hp. These cars usually weighed closer to 3600-3700lbs curb weight. They were more like 3400 dry weight. An old high school friend of mine has a 72. With a glass hood, aluminum heads and intake, no a/c, and a full tank of gas, he weighed 3475. 455s had massive torque, as you listed, but that makes launching a challenge (especially on normal sized street tires), and they have no hp, so they don't pull long at all (no topend). I would throw on a pair of ET streets and laugh at him the whole way.
