cam profile for 750 ls kit
I have a fitech 750 kit installed on my
403ci Ls Twin 68mm Turbo motor with WWCH stage 2 ported heads
81 pound injectors along with hyper fuel 1600 fuel pressure reg and 440gph pump.
I was wondering with a stock LS9 cam should this be considered a cam 1 or cam 2?
Info below states
Choosing a cam selection:
Cam selection is based on vacuum load of the engine. Cam 1 is for 15Hg or above, Cam 2 is for 10Hg to 15hg, Cam 3 is 8Hg to 10Hg, Cam 4 is 8Hg to 6Hg. These are estimates and you may need to switch between them if the vacuum load is between two different cam settings to get the engine to run better for your application.
According to Hotrod https://www.hotrod.com/articles/ls-cam-test-comparison/and LS9 cam has around 20.1 in-Hg at idle
Any info would be great!
