Engine HP?

[STINGER477]

I have a sbc 350 w/aluminum heads, 2.12 Rotator, 80" 3-Blade R Blade Prop set at 1.5 "by the marks on the blades" and its swingin it at 5100rpm WOT. Does anyone have a good "guestament" as to what kind of HP. this engine is putting out?

WELL IF THESE SO CALLED 450+ HP MOTORS ARE TUNRING THEIR PROPS ON THE 3 OR ABOVE THEN U GET A GOOD IDEA OF WHATS YOUR IS MAKING TO ME I DONT GIVE A SHHET AS LONG AS MY BOAT RUNS GOOD AND RUNS WHERE I WANNA GO HP DONT MEAN JACK DIDLEY ... RUN IT AND BE DONE WITH IT AND WHEN SOME ONE ASK U JUST TELL THEM WHAT EVERYONE ELSE SAYS OL 450-500

I would guestimate that you have around 400 HP.

without knowing if it has a chrome breather and chrome valve covers and chrome alternator and chrome oilpan there really is no way to be that close .. if you got a carb that has been actually anodized to a different color that is a bonus as well ... simply giving prop rpms and approx pitch settings is not enough info .. we need pictures of the bling involved .. no blingy no hp .. it has been proven time after time at the boat ramp dyno shops across this great state of flurida ... and how many chrome crankcase beathers ya got .. a good engine has at least two amd maybe more ... gotta letz them hosses breath ya know ....
