Dave, put in the loosest converter you can find. I would go down 2 jet
sizes and leave the timing for the second run. Every combo is different
of course, but I have found that the less crank you have, the more effect
it will have in slowing you down. You don't see many people from the
area building too many lower class cars. There are a lot of A,B,C cars &
a lot of stick cars. The locals know how to give themselves a better
mousetrap. Hope this helps.
