Drag racing total timing,Eddy heads

I agree wholeheartedly with Crackedback and his converter suggestions. If your PTC is not doing the job now, why buy another one ??
My point, I have a similar combo as you, albeit a 904, the Turbo Action 10" I just sold went 1.60 60', and my new Dynamic 9.5 just went 1.50 with the wrong carb. Dynamic's, or Ultimates are more money, but well worth it.
I agree with ultimate, but I quickly went through the thread and think the OP is or was running a TCI converter not PTC.
