hp formula

Could some one please tell me how to figure the horse power of my 289 bore 30 over engine in my 65 fastback? It would be greatly appreciated.

you don't really gain any hp from a bore, so it should be stock hp #'s

The only way to get the exact horsepower is to put it on a dyno somewhere. Most major towns have a speed shop with a dyno.

If your engine is bone stock, with no major performance upgrades, you are probably sitting at about 170 - 180 at the wheels.
