My daily driver 62 chevy and a question

The transmission also is not freewheeling

 

small update, just been messin with it. have my nos factory sized bias plys on it, roof rack and made an air cleaner fit with my varajet on there.

 

i assume you have a relay for your overdrive. a publication i found very helpful in getting it working is "thunder road flathead guide" by bill sinclair. it'll show you different ways to get things going and how to use a mopar headlight relay. in my case (a '50 ford) the stock-appearing relay is over 125 bucks but a mopar headlight relay is less than 20!
