can anyone tell me how to tell the horsepower of my 63 dart 270 6 cyl

Advertised hp 170ci=101 225ci=145. That of course is at the flywheel, hp to the rear wheels much lower. And naturally this would be for a new engine not one with tons o miles.

Also, that is not measured the same way they measure it today. In the '60s, they measured "gross" flywheel horsepower - they were allowed to take off the belts and exhaust, ice down the intake, and a lot of other things. Modern "net" flywheel horsepower is exactly as the engine would be installed in a car. The '60s era 225's would probably be around 110 net horsepower, although it's hard to say for sure.
