273 v8

I have a 67 fastback barracuda that my parents bought new in 67 and i parked it in a barn in 76. Just pulled it out and want to keep it all original, but want a little more fun. I want to basically make it a cammando. Can anyone tell me what cam to use? I am going to 10.5:1 pistons and a new intake to accomodate the 4 brl carb. Any and all other tips will be of great help to me.
