Help me with initial Holley Setup
I'll have to get back to you with numbers. I'm pretty sure most 4150s bigger than 700cfm had the rears plugged for a long time. But I have a Holley book at home that has those factory specs and the list numbers. I had 2 800DPs (the old school 4150s) that both had plugs from the factory in the rear. And the PV channel represents about 8 jet sizes worth of fuel..Depending on what jet size you start with.
