LS3 Camshaft Upgrade - Sticks With Stones Photo Gallery
The stock GM cam falls on the mild side with duration numbers (at 0.050) of 204/211 and lift of 0.551/0.525 on a 117 LSA. After crunching all the numbers we came up with a custom grind of 226/238 duration and a bump in lift to 0.585/0.605 inch. We knocked the LSA down to 114. This combination should net us more power and retain almost all of our streetability.
