I've been doing a little bit of carb tuning the past few days. I ended up using the same recipe of jets, primary and secondary rods that I used in the 1972 T/A project. This recipe was passed along to me from other far more knowledgable members here.

The end result is the following for my original 7042273 carb: 74 jets, 44 primary rods and BE secondary rods. The 1972 7042273 carbs were way too lean from the factory and definitely need more fuel than the emissions lean factory setup, if you want them to run right. The Formula is running the stock 068 cam, a four speed, and a 3.42 rear gear which is the same driveline I had in the T/A.

I gotta tell you, the car really comes alive with this setup. When you hit the sweet spot in the power band at around 3,000 rpm, the rear tires break loose in first gear, regardless on how angrily your foot is positioned on the gas pedal. I'll post some video when I can figure out how to drive, shift and film at the same time...
