carb problem's

Hi, my name is Dave.
I have a ford thndrchkn, I built a 331 stroker & I have a 3310 holley that I can't get dailed in to my satisfaction. My car runs good unless I punch it from a dead stop. This is a big problem for me because I built it to race the 1/4 mile. If I have my rpm up a little when I punch it my car runs great. Can you help me with this? would a diferent power valve fix this? i've tried changing the pump cam's & jets even the pump arm's but I can't get rid of this hesatation off the line.
Thank you for your time.
Dave.

Ya a Thunderbird can be called a Thunderchicken when your having issues with it and it makes you so mad LOL Mine has the 351W in it and I also get that same hesitation from idle to pushing hard on the accelerator. I have been told to check a bunch of things when it comes out of storage. Those things include. Timing, Spark Plugs, Power valve and accelerator pump. Oh and do a compression check on all cylinders too to make sure they are all at the approx same numbers. It also may be too lean or to rich.

Re: carb problem's

Ah okay, I though it was just coincidence that is spelled "thunderchicken" lol, okay just wanted to know what model so I can move it, this is just for talking about technique of drag racing, not parts or problems.

I will move this to the thunderbird section of the Forum.

Good advice re. " Timing, Spark Plugs, Power valve and accelerator pump. Oh and do a compression check on all cylinders too to make sure they are all at the approx same numbers. It also may be too lean or to rich. "
