An overdrive tranny would be the ticket, but Plymouth didn't come out with one until '42. A knowledgeable mechanic friend who also has a '38 coupe says an O.D. trans won't fit through the tunnel on the x-frame without mods. Changing rear end ratios would be better for me if I could find a 3:50 . A T-5 conversion would be great, but beyond my talent to make the mods.
So, it looks as if the rear end gear ratio is the culprit.
Thanks to you guys for all the input and if there are any other ideas, I'd like to see them.
