My 30 cpe, stock with 60 over bore and with 3:78 rear has no problem getting to 65 mph. I drove it to Daytona in 59 and back and forth to Johnson City on regular occasions in the early 60s and would hit 65 on the straights. Of course brakes and steering are a limiter but I was much younger then. My 28 will easily get 45 and if pushed or punished 50 on a straight with stock engine and 4:11 rear. A 3:78 would be much better for it. And for naysayers, both of my T's will easily get 45 and hit 50 on a flat with a little wind help.
