It depends on what is in the transmissions in question, what gear the car wants, and what RPM it turns.

Does your 400 have two aluminum drums and an aluminum reaction carrier? Does it have a straight cut gear set?

Are you talking about a 350 with two aluminum drums? Are you sure the car really wants a lower 1st gear?

Gains from the transmission are measured in hundredths, and the cost to change is often over $4K if you're looking for a killer light transmission. What else will $4K buy you that you need, and will it give you more than a few hundredths?
