I've recently taken on the project of finishing my step dad's 56 Dodge C3. He passed away before he could finish it which is really sad because he put so much hard work into it and was getting really close. He had dropped a 75-78 mopar 440 RB engine (casting 4006630) along with an A727 and 489 rear end. Really cool project and is mostly done! All that's left is basically a top side engine rebuild, electrical, and minor part replacements. I'm to the point where I'm getting real close to starting it, however I've discovered that there is no dipstick. So of course I order one up and slide underneath and discovered, to my dismay, that he had fabricated custom engine mounts to grab on to the sides of the 440 and one of them is slightly in the way of the oil dipstick hole making it nearly impossible to get the right angle to slide the tube in. It's not blocking the hole completely, but getting a chrome dipstick tube to fit without bending it to death was out of the question. But you all know what's like when you're THAT close to being able to start for the first time only to be halted by such a small trivial issue like this. So I thought to myself, "why not just plug the hole with a rubber stopper until I can figure out the best way to get this dipstick tube in? It's obviously going to take more work than expected (removing or altering the engine mounts) so as long as I have the exact amount of oil.......wait a minute what is the oil capacity?? Upon researching 75-78 440s, I discover that they can take anywhere from 5-8 qts. Without knowing what the engine came out of, and without having a dipstick to check this presented a problem. I got under and noticed that it had a 933 oil pan. From my research it appears that the 933 was a 4 qt pan. So does that mean it's 4qts plus one for the filter equaling 5 qts total? Or were there some 440s that took more than 1 qt in addition to the 4 qt pan? So i'm stuck. I'm not sure what the best course of action is at this point. I don't want to spend too much money figuring out the crazy dipstick issue because upon starting the engine for the first time I might discover other things that need replacing. Any guidance would be greatly appreciated!
