Guess my 273 hp

I did some work to heads. Cleaned up casting. Gasket matched and smoothed edges under valve. Carbs seem well matched to setup. Plugs are good Color. Total cfm for Carbs is not 900cfm. There is not secondary squirters so its not loading up with to much fuel at higher rpm. I'm sure a dual plane intake would be nice but far less fun. Intake is one of the better ones for a street car. I'm sure its putting out more than 200-240hp. My build 318 I had was putting out more than that and this motor has a lot more go than the 318 did. Its all a guess really.
