Pete,
My step-son has a stock '51 Plymouth with a 217. I can understand why you wanted an overdrive! That sucker has so much low-end torque that 1st gear is NOT necessary when taking off from a start. However, at 60 mph on the highway it seems to be screaming. I've never built a flathead MOPAR, but your engine looks so good......and it's different, so I just might get one and do something like you did. I enjoyed your site, by the way.
