Brian Tooley Racing GM LS 388ci+ Turbocharged Camshaft

This cam has gone 4.50s in a single turbo 388 and in a twin turbo 427. These numbers are very near the ceiling of what is capable with a hydraulic roller in a 3000+ lb chassis. This cam will take you to the promised land with the help of a pair of medium sized turbos or a single GT55-level turbo.
