Okay just an update on the work. tried the slant 6 engine in my wife's valiant and drained about 3-4 gallons of water out before the oil came out. For a minute there I thought I must have been a dumbass and drained the oil last fall and didn't add any. Then I remembered oil is lighter than water, so it floated up to the top of the engine. pulled the plugs, removed the carb, rad belts and hoses. Added diesel into the intake till it came out the cylinders and then manually turned over the engine, drained everything and added oil. Hope it works. Gotta drop the tranny pan and change the fluid there next. I think we will do the 440's and some of the 383's next, probably will not get to all, bummer.
