[BIG HOSS]

Depending on which one you have there will be a lean/rich screw in the back of it some have a 3/8 bolt with a spring some take a 1/8 inch Allen wrench just play with it till you get it where you want it. Timing should be run at whatever you normally run and I run the autolite race plugs in mine there kinda pricey but do the trick for me. You can get a Holley base plate that has the vacuum port on it or drill your intake and put a fitting on it I have done that on previous motors and it worked well.
