Mostly been said right in the posts above. But my votes for chassis numbers when I am trying to figure things out regarding how a car actually runs. For example when I switched to a glide from a built T.H. 400 I gained about 35 horses across the board. Gained about 8 horses across the board by changing my rear end housing over from a big bearing to small bearing setup. That latter setup also had a much more stout housing BTW. There is something to be said about rolling resistance numbers too. I never think about peak numbers, only compaired numbers. Personally, I think peak numbers are worthless and flywheel numbers are only good on a inital fireup and cursory tune of a new engine. Of couse there is the added cost of continued visits to your local chassis dyno shop to consider if using that method ,,,,,,,,,,,
