Carb swap, and all the adjustments with it.

If you drop the primary jets down one or 2 sizes and lean out the idle mixture you can put the float level back up to BG recomendations. Personally the Holley is a better carb than the BG...they are similar but they are very different. What PV do you have installed? The PV should be 1.5" less the in gear idle vaccum.
