determing engine HP

Is there a way to estimate the horse power without putting it on a machine?

I have a 327, bored 40 over, with a 3/4 cam and solid lifters. It also has dual edelbrock 500 carbs.

HP rating

without knowing what cam, heads, intake, size of headers, cfm of carbs, bore size of motor and the stroke no-one knows~!

So, dyno-up with the cash and pay the fee~!..I am willing to bet you'll be shocked at how little power you really have...From the pic, 1,00000000000 ohms of RESISTANCE~! Dyno-up~!

Yea that is what it means, a full would be an all out race cam, but I don't think I have ever heard anyone mention a 1/2 or 1/4 cam. But what constitutes as a race cam. And by those respects anything in between 230 to 250 degrees duration at .050 could be considered 3/4 race. There are a crap ton of cams that fall within that range.


Either way to the OP, if you come up with the rest of the specs of the motor, we can probably help you out.

horse power

Sorry, I don't have any more information on the engine build, just what I was told when I bought the car. I just thought there might be some simple calculation used to estimate HP. I'm not interested in putting it on a machine to find out. All I know is it is a blast to drive and is very fast.

No big deal, the "3/4 cam" phrase is a 60's era thing and really doesn't mean much. To really guess at hp....and that's all it really is, you need to know just about everything in the engine. A warm 327 could be anywhere from 275 - 350 hp....who knows. Enjoy the ride
