Re: New track times...still not happy
What are you running for total timing and what distribtor? Also, could you post all the timeslip data? Like 330', 1/8 mile &MPH, 1000', etc?
I ditched my Carter 625 for a holley 650DP and the car dropped 3/10ths and a total of 6/10th when I got a handle on the jetting. Walk through the pits, everyone fast has a holley or a demon carb, there is a reason for that. Look don the airhorn of the holley versus the carter-no doubt as to which one is going to have smoother flow into the engine. I would try and get a few more tenths out of the current combo (minus the carburetor) before switching heads.
