4 bbl intake 273

Everything about the car seems stock, so the 273 is bolted to a torqueflight 3 speed 1st is 2.45:1 2nd is 1.45:1 3rd is 1.00:1, also the car is a small block, I'm not overly mechanically inclined yet however comma I can definitely figure stuff out. So you recommend some change to gearing a torque converter stall converter thing?
