Inliners International Forums General Discussion Hi Performance Initial Tuning for Holley 4-Barrel Carb Model 8007

Leave the stock jets in and start tuning the secondary opening rate. Start with the short Yellow spring. Watch your 60' times.

Also try leaving just above an idle and let the converter "flash". Again, watch your 60' times.

After you get the best 60' times start playing with the jetting and jet for the best MPH.
