If anyone is serious about learning how to tune your Holley.
I Found some real good stuff on Holley carb tuning. Get out your study cap and reading glasses if anyone is interested.
I myself am in the process of doing these things to my 850 DP. I ordered all the plugs, drill sets & Taps etc to make this happen.
Most will pass by this information and live with their issues. The Die Hards will take it to heart and go for it. I am using a wide band. If you do not have one. Spring for one. A UEGO by AEM only cost about $200.00
