I wonder how much of a gain I will get!

Coyote Jack said
If the entire assembly was siezed, I would imagine that you will see a huge gain. Is it possible that the previous owner had the vacuum and mechanical advance locked out and was going with all of the advance 100% of the time?
I see your from Maine. Are you going to the Atlantic Nationals in Moncton, N.B. this weekend? If you are, a few of us will be there on Saturday and some on Sunday.

I dont think it was locked out on purpose,it was all corroded and its quite crusty inside,its not timed with any real advance,,well its at 8btdc,I wont be going to the mopar nationals,If I would have know about it sooner it would have been a possibility
