yes exactly, one of the reasons I really enjoyed it on my first small road coarse race.

pretty sure no, other than GM uses a 16 tooth reluctor wheel for the VSS sensor vs a 40 tooth reluctor for 4l60e and 4l80e so you just need to make sure you have the right settings for your speedometer and EFI.
