AMC 360 stock!

Did the math out today, yup 6 MPG . I knew it was bad but cmon now.

Where do I start?

None of the vacuum lines are hooked up so I am goign to start there, But I dont know what year the engine is out of so Ill choose one schematic and go with it.

Next I have a HEI coming on monday so im going to install that next weekend, as well as set the timing.

I feel it idles high also, could that have anythign to do with it?

My carborater is a MC2100, I am not 100% sure though. In May I plan on going to TBI so that would fix all carborator problems. But would could I do in the mean time?

Sorry for all the questions, I just want to beat somone in the face though!

Please Help
