Nothing really special about the 85's other than it was the last year of the G-head. All later years run the swirl head. Take a look over in the knowledge base section and forums over at turbo-mopar.com for some info. Another useful resource is minimopar.knizefamily.net they have some decent reference info there. Basically the first thing most previous owners of these cars do is [Edited by Moparts - Family Friendly Site - Keep it clean] up the vacuum lines not knowing what they're doing. If you're having any run or boost problems, check that first. The shelby chargers are cool little cars, I used to have an 83 Shelby Charger with the 2.2HO carb. Not the fastest car out there but it was a blast to drive and it was the blue/silver two-tone and it was a cool looking little car.
