      I've stopped at one of the stores there a few times driving through.
      Looks like you could drag race anywhere...

      The tracks only 7 miles out of town. And no, you can't drag race everywhere........We still have a lot of dirt roads :D

        Just watched the weather. looks like mother nature is sending some of this storm north of us. Aka your way j-par
        It may still be two wet to race though. Hope it trends farther north by Saturday.

        They should put instruction that if you want to us the squirter pump, you have to do some drilling!:(

          Seems like a screw up to me.

          I’d call them and see what the story is.
          If the bowls aren’t supposed to be finish machined and ready to assemble...... I’d just send them back and get the QFT or Proform bowls.

            Well to make matter worse, i ordered two secondary bowls:BangHead: so the front one would be facing the wrong way for fuel inlet and sight glass.
            not going to be ready for this week end... i guess i could make the $50 holley 3310 donate it fuel bowls just for testing.......going to have to think on this......not sure they will even fit..... we'll see.

            Did you get secondary bowls for a vac secondary carb?
            If so, the acc pump holes would all be blank.

            Those PF bowls are looking better and better.
            My recollection is they have dual fuel inlets and sight glasses........ can be used for either primary or secondary.

              All true. The PF bowls are by far the better deal.

              Didn't have time to get the demon carb back together and didn't do anything to the proform one, same as last race.
              Stumble is not 100% fixed but close. It stumbled the first test run but not a fall on your face stumble, more of a slight hesitation.
              Ran flawlessly the rest of the day. and was vary consistent as well.
              ran 7.94s to 7.93s all day long
              Made it to the final round of competition and punched a RED light!:BangHead:

              Temps were in the 50s and low 60s all day sun shine and no wind.
              Was a real nice race day.
              Had the GoPro on the roof of my car for sever test runs and then tried to set it up to read the o2 meter again.
              haven't downloaded the video to know it its even visible on not but will let you know or show the video if its worth while.

              Any hooo great day, didn't break anything and another racing season in the books.

                Well i was hoping that this video would give me a little insight. but not really.
                with the GoPro on the roof of my car i was hoping it would show me something. It darts left to right, but i already know that.
                slowed down the video on one launch but then you don't see it sashay around at all.

                The last half of the day i decided that i would put the GoPro in the back seat and see if it would pick up my o2 meter, to see how the carb was behaving threw the pull of each gear. NOPE even on my wide screen TV...........to far back bad angles Just nothing.
                The last run when i red light you can see i just wasn't ready and CHOOOOKED!:D
                But its only 6 minutes long so here you go any ways.
                Injoy!!!!
