Carbureted Intake for LS1's - New Dog, Old Trick
To swap the valve springs the coil packs need to be removed. Each coil is mounted to a common bracket that is bolted to the valve cover. Currently there are no higher output coil upgrades, largely due to the fact that the drivers that control the firing of each coil are built into each coil. This makes it a challenge to aftermarket engineers in cost and design. It is said that the coils used on trucks have slightly larger heat sinks making them more desired for higher horsepower applications. Truck coils are more triangle-shaped than the rectangular LS coils and the plug wire tower is in the middle of the coil compared to the bottom. View Related Article
