I'm with P.J. on this.
I have a 64 with a 350 (not hot rodded-in fact it runs a 2 barrel), 700R4 and a 3.08 from a 71. Doesn't matter if the overdrive is engaged or not 15 to 16 mph. I do believe that in 40 years the auto makers could do much better than that (in a full sized pick up) if they wanted to.
And yes I do enjoy the fact that I have that ear to ear grin while driving mine.
