hey guys whats up, well my lucky cousin picked up an 88 notchback for $800, it runs and everything but it sounds like its seen better days, we are trying to replace everything needed to make it run like a champ again, so far we have replaced plugs and wires, cap and rotor, thermostat, water pump, radiator, coil, air filter, we cleaned the MAf, we also checked the compression on all 8 cylinders, they all show 150 except for one that reads 140, does anyone know what the stock compression should be at? also is there anything else you guys would recommend replacing? thanks in advance.
