i dont know about those flow numbers but sounds like the holley 950 which actually is only 830. The 4300D ive run for the last 10 years only flows 580. Now thats real word numbers on the WET flow bench. Im sure it could be more if i dry flowed it but it does have to mix with fuel so thats not actually. No power valve, plug 73 and 86 jetting never change it just leave it alone the flap stuck once last year at kinston at the points race so now i just keep some 3 in 1 oil and check it ALL THE TIME.
