First steps in tuning a holley double pumper?

I have a 355 sbc that I just got exhaust on and tied up some loose ends with it. It is in an s10. I have a holley double pumper with an airgap intake and headers. I have a 278 cam with a 450 lift. I have the truck timed and have the float set. What are my next steps in tuning the carb? And how do you do these steps. Im really new to carb tuning. It is a mechanical secondary. Thanks fellas.

Drive the car and see how it runs. You may not have to fool with it at all. If you do start to "tune" it. Only change 1 thing at a time and keep notes so you can go back to a baseline. If it runs good try to resist the urge to fool with it.

Mortec.com has some good Holley info as well as several other sites on the net. If you do decide it needs tuning. Read first and understand what you have read then you can attempt changes.
Holley's are fairly simple but are also easy to goof up.
