Best bang for the buck?

  • What is your initial timing?
  • What is your total timing?
  • I would guess your current combo as it sits would like about 22* initial and 40* total.
  • Have you warmed it up, pulled the plugs, pin the carb open and done a compression check?

Low compression small blocks like timing.
Converter and headers will help a lot.
When you get the money, a reverse manual valvebody.
I did not notice what carb you are running. Make sure it is opening all the way.
