Not Ranked
Thank you all for the suggestions. I did pull the choke blade before I even put the Holley on. Also, I threw in a new set of plugs which gained me 10hp but the numbers I posted reflect that increase. Exhaust is as open as I can get it. Headers to SpinTech box and then out the side. Air filter is new K&N and the pull I noted was without the filter. I went to a medium spring on the secondaries so it is responding faster and they are opening well as far as I can see by watching it during the pull. I didn't try the jetting reduction so that may be the next step. Any thoughts on going to an 830 double pumper with manual secondaries and no choke? Everyone says that a 750 is plenty but it seems like the beast needs more fuel. Thanks again and by the way - I love the bouncing icons for 392Cobra.....
