HO565-300K - HYPERSPARK IGNITION KIT, CHEVY

Suit Small & Big Block Chev

Part Number: HO565-300K

Holley HyperSpark Master Kits were designed to make upgrading your ignition on a Sniper EFI-equipped engine simple. When installed concurrently with a new Sniper EFI system, the combination creates the easiest to install EFI conversion on the market - only four flying lead connections required! This harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power.
The pre-terminated connectors and a built in 40A relay provides power to all of the components within the system. With the included Sniper EFI Main Harness you no longer need to run multiple wires to provide switched power for each individual component. This not only helps prevent wiring confusion, it will speed up your install time and clean up your engine bay. Just route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in.
Features:
Plug and Play Sniper EFI Main Harness replaces the standard Sniper EFI harness with four loose leads, Battery Positive, Battery Ground, Switched 12v, and Fuel Pump Power, for a simple and streamline installation
Designed for existing or new Sniper EFI installations. The HyperSpark Master Kit harness retains the same flying lead wire colors as the Sniper EFI main harness. New installations will not use the Sniper EFI standard harness or coil driver
Complete Ignition system in a box, including: HyperSpark Ignition Box, HyperSpark Ignition Coil, HyperSpark Distributor (for your application), and a plug and play main harness
HyperSpark Distributors feature a Hall Effect crank trigger sensor providing a noise-free RPM signal to the Sniper ECU
Patented Clear Installation cap eliminates any confusion while installing the distributor
HyperSpark CD Ignition box is seal and powder coated to be installed in the harshest of locations
External LED on Hyperspark CD Ignition box helps verify 12v, cranking RPM, and low battery voltage
135mJ of spark energy when used with the HyperSpark Ignition coil, ensures complete combustion
Integrated ignition coil bracket simplifies mounting the Ignition coil
Ignition coil connector removes any doubt of loose connections at the Ignition coil
Enables timing control on a Sniper EFI Installation

Quality could be better
Really cool product but quality is not the greatest. I have tried three times and my GSD destroys them within a hour. Feel the stitches are too light and easy to rip

Dogs love this toy!
I've purchased a couple of these and the dogs love them. Good for puppy teeth and adult chewers. Can be torn up but last for dogs that like to chew.

Beware not as described!
I have ordered these multiple times in the past because our pup loves them. However, what I received this time is much smaller than before and does not match the dimensions on the site (6 in versus the expected 9). Very disappointed since I ordered two and these are not cheap toys.

My Bulldog’s Very Favorite
These are the best toys! My bulldogs love all the different shapes and sizes and I buy multiple per year. I feel comfortable with the safety of this material, even though they start wearing it down very quickly.
