Built 273, what sure grip ratio with a A833 3.09 first gear

run it with those old tall tires and the 3.55 gears, that will give u an idea about those who have suggested less rear gear like 3.23. snow tires may seem to be soft, but they put less rubber to the pavement. and ancient tires will not last long. your initial post asked about what advantage to changing rear gears-but you did not say what u are looking for - more revs, more gas mileage, quicker acceleration, what. stick with the 3.55 gears and go play with as wide a tire as possible

Fuel economy is not an issue , since it's only driven for a few months out of the year . I'm not worried out burning up the snow tires . I'm not drag racing the cuda but I'm looking for quicker acceleration . I may occasionally jump on the freeway heading to a car show ( maybe a few miles) , If I stay at 55mph with the 27" tall tires I don't think the engine will be screaming that bad with 4.10 gears . Just thinking 3.55 gears and 27" tire , the cuda will be a dog all around. I like going fast ! lol I use to drag race a 65 dart convertible with a mag crate 402 stroker that ran 11.3 on the motor. 10.9s on the bottle.
