Yes, the same as if it was in the car. Block it up good, make sure nothing that rotataeswill hit the ground as it rotates. Pull all the plugs, prop the throttle open. Do not hook up the coil. Get yourself a charged battery. Take a set of jumper cables. Hook the + cable to the starter big post, and to the plus battery post. Hook the neg to the battery neg post. The other, hook to the engine ground when you want to crank it over. After you put your compression gauge in the plug hole. Does this have a starter mount solenoid? Oh, just looked at the year again. If stock, it will have a fender well solenoid. Do you know how the wires hook there, and at the starter ?
what damage is done if you dont pull all plugs and not open throttle? I checked my '67 Falcon compression by pulling a plug at a time, and I never opened the throttle.
