Here is the result of the 850HP Street with a Proform body. I went with #72 in the primary and #84 in the secondary. The largest PV that I currently have is 6.5 so that’s what’s in there. I’ve got pink cams in the first hole with 30cc pumps and 031 nozzles. What secondary throttle plate opening should I start with? I’ve seen some people take out the secondary throttle adjustment screw and put it in from the top. Will this work? How many turns out from seated should I set the idle mixtures screws to start with?
Thanks again for the help!
