AJ's Opinion; what size SBM do I need

I'm not unfamiliar with small displacement engines, I built the 30 over 289 for my 64 Fairlane, it made 455hp and 445 ftlbs of torque NA. Now I could have bought a 362 from Ford that makes 500hp for less money than I have in the 289 but in would not have been a 289. So I understand a loyalty to one particular engine, the car was a 289 so I built the same, but if I was just building a mild to stock daily driver I'd build a 360.
I love '64 Fairlanes, and I love 289's !!!!!!!! Although '66 Fairlanes are my favorite, the '64's have a special place with me, and my child hood !!
