The Crane HI-6 Ignition for the LT1, part No. 6000-6440. Most of the little parts you see here were not used in the installation, since this kit actually covers a much broader range of vehicles. Really, all we ended up using were the box, a couple of screws, a few electrical connectors, and--last but not least--the instructions. Crane's suggested retail price is $284.70.
