They are pretty close. The L82 has 222 vs 214 degrees degrees intake duration at .050 and 114 degrees LSA vs 112 for the Summit cam but otherwise they are about the same. I doubt you could tell the difference driving them back to back. That basic spec Summit cam has been around for a lot of years and offered by many different Cam companies. I have it in my 69 C10 with a 9.3:1 355 and 3.73 rear gears under a GM Performance part number that says manufactured by Crane.

Could very well be a Crane grind.
