I'm taking my Mustang to the track (any guesses on how Fast)

I'm assuming you went from 30cc pumps to 50cc..? We have very similiar setups I'd like to get 12.6's out of mine too.
What size PV are you running?

The Carb is stock beside what I did to it. I don't know what power valve is in it. The reason why I put the 50cc accelerator pump on it was for the Spray.

I had to put a 50 cc pump in my 625 Road Demon when I changed cam ( 218/218 to 224/230 @ .050) and to an Edelbrock Air Gap. I also had to open up the pvcr's some as well as open up the low speed air bleeds a little. Suprised me some to have to do all that to get rid of the lean bog and lean stumble at cruise speeds. Also had to play with the secondary vacuum springs some for best results.

I don't think there's any end to the carb tuning one has to do when changes are made in other areas. Mine does have to remain streetable.

REV...what size converter do you have now and what are your 60' times? You just need a little more ummmmph to crack the 12's.
I'd like to see your beast break the 12's too!
When you do break the 12's, you'll be like me and wanting 11's then...LOL....but I'm going to "juice" my way into the 11's though..LOL
