Default Compression Test

Anyone have normal specs for LT-5 compression or tested their car?

dont know if altitude plays a part in testing compression. my black car tested at 175 -180 cold my altitude is 4000 ft . did they all test 210 on the left side / did you have the plenum and inj housings off? if not was the throttle held open all the way?i wonder if the cam s on tthat one side are timed different. dont know if that is possible ,just sharing thoughts .hope it helps
