Well my 93 lt1 has antifreeze in the oil so I started to a compression test. With wot and all plugs out dry results are 84,85,85,95 on left bank 85,85,85,95 on right bank theese sound low to me any idea where I should be for a stock 93 corvette lt1???

Your compression pressures are too low. Shoot some oil in each test cylinder and retest. The antifreeze might have deluted the oil and washed the cylinders clean. You might have to drain the oil out of the motor if the test fails again. A min. pressure should be a no lower than 125psi.
