Product Details
Part No. 550-511-3PK-SBC
Warranty Details (2 YR REPLACEMENT IF DEFECTIVE)
The 1 selling EFI conversion just got better.again! We're bundling our top selling Sniper 2 packages and passing along maximum savings! Available for small block Chevrolet, big block Chevrolet, and 8.2-inch deck small block Ford (5.0 base), these kits include a HyperSpark distributor, HyperSpark coil, and a HyperSpark 2 ignition box. Coupled with a 3.5" or 5" color LCD touchscreen handheld, Power Distribution Module (PDM), and either a base or master (in-line fuel system) Sniper 2 kit, these are the most complete Sniper EFI conversion kits ever offered by Holley. The PDM module was specifically designed to provide the easiest wiring experience for Sniper 2 kits that are paired with a HyperSpark ignition. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screws. Battery power, ground, and a switched 12V source are all that's required from your vehicle to power the PDM and your Sniper 2 system.
