Hello everyone. Just switched carbs and now have a Holley 650 double pumper on a 13b 6-port with half bridge. I'm sure I can figure out all the right settings if I had all the time in the world to tinker every day. I don't so Inaas hoping someone would be willing to share some of their wisdom so I have at least a good starting point. Other related mods include MSD ignition, full RB exhaust, and RB intake. Looking for a good starting point in regards to jet sizing, squirter size, accelerator pump diaphram size etc. Also I guess I should also ask about a good starting point for timing. I.e. How much advance or retard and also how much difference in degrees (lead/trail)would be recommended with this set up. I realize that your suggestions will be general but like to save myself some time and start from a relatively close set up. Thank you everyone. Hope everyone has a safe New Year.

 

Does it have screw in air bleeds, or pressed in?
