Building out a 273 recommendations

Hello,

I just recently bought a 1966 Barracuda with a standard 273. It was suppose to be a commando, but was misrepresented by the seller (reimbursed me some $$)
I plan to pour about 7 to 8k into the car, more for reliability (first classic with wife and kids). I do want some performance. I would have been happy with 235hp or a little higher but . . .
The PO did install an edelbrock manifold and a small 4bbl (500cfl) (to his mind, this made it a commando)
Anyway, I am thinking about upgrading the cam (a purple cam from summit 284/284 duration and 484/484 lift) and a couple other features (larger carb, 600-700 on the 273) and wanted to ask your advice, recommendations and experience.

The body and interior are super nice. So the car is a keeper even if the motor wasn’t quite what it was suppose to be. My goal is a nice classic car with some pep, not a true hot rod. So sub-300hp is fine. I prefer mid-250s


Again I am working toward a classic with some get up and goooo

thank you for any help and advice
