Howard --- the original jets for the 4055-1 center carb were # 63's. The outboard carbs had metering plates (machined orifices) and no screw-in jets.

Howard,

The stock setup for the front and rear carbs would have been a #76.The stock center carb would have been a #63 for a 4sp and a #61 for an auto.

Dan - I am confused by your commments on the #76 jets in the front and rear carbs since they contain metering plates versus metering blocks with chanageable jets....Craig

Re: Original Jet sizes for 69 Holley 3x2

1969 Shop Manual also shows #76 jets for the 2300 secondary carbs, which don't have jets - maybe they mean metering plates with #76-equivalent orifices? The Holley site just shows "N/S" or "N/R" for metering plates for the 3659 - no detail.
