LT-5 performance upgrades? - ZR-1 Net Registry Forums

Just dyno'd at 530 CSHP. Pete did the work. My wife is learning to hate it.
The single mass flywheel makes the tranny noisy when sitting still. Sounds like the engine is coming apart.
I reduced rotating mass, 15# flywheel, light weight pulleys, plus reground cams. The car is lurchy when moving at an idle, like in stop and go traffic or parking lots. This was a side affect I had not anticipated.
