Should I replace the stock 360 intake?

IIRC, a 70 is squarebore.
A ‘71 is for a TQ.
MoPar said the square bore intake is good for 10 or 15 hp, but, IMO, it was due to the carb up top having more flow. I do not know if they tested it in anyway. IE swap carbs on to the intake and test. AFB/AVS s a TQ.

I personally am not so fond of that year because of the choke well cup. They rot out. Repairable? Yes, to a degree. Recently, there made of unobtanium.

Im not sure about a ‘72, but a ‘73 has a different style choke well. Much better. Chokes available.
