Dyno testing a stock(?) 1972 440

I was looking at the year by year specs on mymopar.com (yes I know they have a few errors), and it seems that the baseline of the dyno test is pretty dang close to what the spec is from the factory.

I wonder how my '69 10:1 motor would do with the same mods...

...and I also noticed the specs say 10.1:1 for the non HP 440 versus 10:1 for the HP. Wonder what the deal was with that?

Again- thanks for doing this wonderful "scientific method" dyno test for us.
