383 intake / carb help for my 73 Dart

definitely dont go back to the stock intake. unless you want to plop and extra 50 pounds back on the front end of the car.

your current intake is probably fine (unless it's cracked or something).

i'd recommend getting a rebuilt carb. the documentation that comes with the carb will probably show you which hose connects to which port, and which ones should be capped off.

like the diagram here: [ame]http://www.holley.com/data/Products/Technical/199R10219-3rev4.pdf[/ame]

it clearly shows where to connect the PCV, the distributor vacuum advance, and the accessories port at the front for vacuum operated stuff (air grabber hoods, etc.)

i'd recommend getting a rebuilt carb that comes with documentation so you can do it without a lot of guessing :)

i'm not sure the best model carb to fit that intake however.
someone else make a carb recommendation. you can get rebuilt holleys or rebuilt thermoquads. (i used a rebuilt thermoquad and got pretty darn good mileage)
