The ZL1-1LE is listed at 756 rev per mile, so I suspect it has a slightly different calculation used for its speedo calibration.

Interesting info.
Does anyone know what the differential front to back tire sizes or ratio is that causes problems with the ECM or ABS (not sure what controls this) reducing power when drag racing? I've heard about a fuse pull work around to remedy this, but also heard that it also cuts out the power steering.
