TQ question

I ran a 71 TQ and stock intake on my 273. On the street, every day, for years, Stock, it made a believer out of me. It was still breaking into 13's in the quarter with a 100,000 mile 340 in a Duster before that. I never understood why they always said to go with a 72 or newer...

There was a recall on the 71 carbs for some reason that may result in fire, can't remember what the exact problem was but when you went to the dealer they swapped out the 71 for a 72 carb.
