I wouldn't do it with power washer on an old truck.
things I've done in the past:
start the engine for like a minute, so the block is warm, but not hot.
take out the battery, cover up the plugs and distributor/carb with tarp and rubber band.
spray some engine bay "Gunk", let it soak few minutes, rinse off with a gentle spray from garden hose.
"dry with a blower", make sure hit all the pockets which can keep water.
blow it over again.
