Tuning LT1 Stocker Cam

Dan Fahey · 08-22-2021, 04:32 PM

Installed Stocker cam and runs great except at Idle.
Using the Pure Stocker a in file.

Runs rough at 800 rpm begins to shut down.
Figuring not getting a good vacuum with a much larger duration cam.

Will run at 1250 rpm but rough..
Runs through the upper rpm fine.

First step will raise Timing from 27 to 31 degrees see how that works.
Hoping that will work some.
But gut tells me other tables need to be tapped.

Are you still running a factory ECU?
