I agree with acadianbob.
My 97 had 3.55; and Nick has 3.73's. The difference is barely perceptible.
Actually, I think the current truck is doggy off the line, since it has a 1900 RPM stall converter -- and the 97 had a 2600 RPM (I think) stall converter.
The new truck tows quite well, however -- and I'm towing the same trailer that I've had with a 6.2Diesel 3.42 and the 5.4 3.55 and now the 5.4 3.73.
The only thing better would be the V10.
The gear ratios with the 3.73 are PERFECT in all gears -- nice work, Ford.
