Would this set up be desireable in my 66 Cuda?

I picked up a '69 318 for free. It is nothing special, '70's smogger heads, 2-barrel. I put my 273 commando intake and carb on it and it's in my '65 Barracuda now, runs great! I don't think I'd pay good money for any kind of 318 without a guarantee of how it runs and the mileage.
