66 Barracuda

Hello FABO,
My Cuda has the original 2bbl 273 engine with the 904 trans. I put new 15” wheels, front disc and a new rear end. So I know it’s no longer an “original” 66 but I’m thinking about rebuilding the 273 so I was wanting to get some advice on what I could do to give it more horsepower. And I’m not looking for advice about a 318, 340 or 360. I appreciate the advice….
