Best Gears for a 408 Stroker?

RonsSwinger said

I have a Swinger with a 440 conversion currently running 355’s (28” tires). It runs around 3000 rpm At 60mph. I find the revs high for my liking and the cabin is loud for any distance driving. My ring and pinion are noisy so I have ordered a set of 3.23’s. I live in a rural area so all my driving is 50mph +. I hope to swap them in about 3 weeks. Car makes lots of power (460-500hp). I think I will be happy with them after running 355’s. (Time will tell). Ron D

I calculate the 3.23 gears will drop the highway RPM to about 2700. I would consider an overdrive transmission. With that 440 torque is not a problem to maintain your speed. I would be looking for cruise RPM of 1800 to 2200 for fuel economy, noise and wear.
My 2000 Dakota POS with the 3.9 noise maker is running right around 2000 RPM at about 62MPH. 400+ miles on the last tank of gas. I live about 8 miles out of town so back and forth with a trip to Edmonton and return making about half that miles.
