600 cfm holley double pumper questions

hey guys i bought a holley 600 cfm and a holley 750 carb with a new performer intake for 200 off craigslist. the 600 double pumper is jeted with 50cc jets i was told but needs a Accelerator Pump Conversion 50cc Kit. it has the stock 30cc right now, would i need two of these kits? or is it easy just to change the jets out?

Re: 600 cfm holley double pumper questions

There are no jets for the accelerator pump circuit. There are squirters but they are not specific to the CC of the pump. You should probably search Holley's site. There is tons of good tuning info over there.
