Completely missed those............embarrassed!
This may be an issue:
User Note: The GM Performance Parts LS 376/520 crate engine (19171225) comes equipped with the LS “ASA”
Cam (12480110) which is an aggressive high performance camshaft that may cause slight surging below 2500 rpm
under light load. This should be considered a normal functioning occurrence given the aggressive nature of the LS
ASA Cam. This surging can be avoided by increasing either the rpm or throttle of the engine at the same given
velocity. Under full throttle usage, you should not experience any surging when using the GMPP ignition control
system (19171130) and the recommended LS376/515 calibration.
That is just above cruising rpm for my car.......
