It's 1 hp to every 25cc on carbs and 1 hp to 22 on efi give or take a little bet
Answer:
Horsepower and cubic centimeters or inches have no correlation whatsoever to horsepower ratings, Lets look at some examples;
1. A 750 c.c motorcycle engine produces well north of 100 hp, a 740 c.c. Briggs or Kohler produces around 25 hp
2. A 125 c.c Motocross bike produces around 27 hp vs. a 160 c.c lawnmower engine produces around 5 hp.
3. a 3500 c.c. Formula One engine produces 1,000 hp vs 3800 c.c GM v-6 produces 205 hp.
4. an old cast iron 850 c.c Kohler K-series (K-532 twin) produces 20 hp vs an 800 c.c snowmobile produces upwards of 140 hp.
These are a few examples to show that cubic centimeters has no relation to horsepower. However, if you had mentioned what 420 c,c. engine you were referring to in your question I could have provided you with an answer for that particular engine.

CC (cubic centimeter) is a measurement of displacement used to identify the size of the combustion chambers in an engine. HP (horse power) is a measurement of power the engine can produce. CC and HP are not the same.

Volume and HP do not have an absolute direct correlation. Between 4 and 5 HP would be a good guess.
277 cc converted into horsepower?
I understand that a 250 cc engine is around a 15 hp motor, so a 277 cc engine calculates about 16.5hp. there is no direct conversion between cc and hp because cc is a volume and hp is a energy.
