. I have 120 pounds of pressure in every cylinder is this both wet and dry test? 350CID should range from 160-180 psi w/ a tolerance of 20% up or down
The smoke is it blue in color?

alfull low compression if wet tested. blue smoke with low compression sounds like a tired bottom end of the engine. blue smoke puffs when hot and starting is usually valve stem seals. blue smoke when running usually bad rings on pistons. either allowing oil past the rings into the combustion chamber or pressurizing the engine enough to suck oil through the pcv into the engine . good luck
