Hi Everyone! New to this site but read a lot of what goes on here. Site is great and a ton of info. Thanks. I'm baffled and need an answer do hoping I can get an answer. First off I am not an owner of a Stang even though I love 'em. I own a '71 Maverick Grabber running a 351 C. After a 10+ year rotisserie restoration car is finished. I replaced the oil pan because it was dented when purchased and my question comes. Why can I only get 4 quarts of oil and a 12oz. Bottle of zddp in the pan and is a hair over full on the dip stick? Is the wrong stick in the car or was I shipped the wrong pan? But what 351 would only hold 4 1/3 quarts oil. I'm stumped. Very good pressure at 80lbs. And about 40 on idle. I'm confused?
