Most of my driving is between 40 and 55 on country roads. I am about 50 miles from the foot hills so for the most part the roads are flat with the occasional small to medium sized hill. I am looking to put a 3.27 into my new project a 1931 Victoria as an alternative to an OD.

The Mitchel OD at 26% with 3.78 gears is wonderful......I have one in my 29 Phaeton and love it. Top end in overdrive is well over 60 but you could drive all day long at 55 to 60 without issue. That said I do not want to go much over 50 with most of my driving. The car will do it but you need to think about the limitations of a car designed for use 90 years back. That said the 3.27 is the equivalent to a 15.5% full time overdrive with 3.78 gears.

Starting off in Mitchel high with the equivalent of 3.00 to one gearing is to much and too slow to get up to speed. The 3.27 should be a slow start but doable and happy between 35 and 50 in my opinion.
