I've read quite of posts about the changes to make on these carbs, but didn't see anything about the accelerator pump size. It shows a 30 & 50. Going on a 2.3 short rods (5.2) .040 over, stock intake with no modifications, stock valve size & no porting, shaved down to intake bolts. running on 4/10 banked dirt. Thanks - F-9

350 cfm will be more crisp on your engine.

Use the 30cc pump and turn it down. Will help with pull over as you really don't need accell pump at rpms. You have enough vacuum coming thru the venturis to create good signal.

Turn it down? could you explain, I am not sure what that means.

Thanks
