If you have a big block Mopar I'd spend the extra $100 to get the 4150 style Sniper. The cables come out the back, the timed vacuum port is in the front, the throttle linkage lines up better with a stock bracket, etc. You do have to buy an external regulator so that adds some money and you might need a dual inlet type of feed so that might add some money depending on what you currently have for fuel lines.
