So I have a 70 d200 with a 383. That motor isn't matching numbers but the truck origanily came with one. The number on the oil pan is 187. My service manual says the motor should hold 7 quarts, but the dipstick says it's full at 4. Do I have the correct oil pan?

Is this a front sump pan?

Do u have the correct dipstick?

Yes it's a front sump, as far as the dip stick goes I'm not sure either the truck was kind of jacked up when I got it so there's a lot of unknowns as far as what's original. This is my first car so I don't have a enough knowledge to know

Google pictures of the engine and compare pans. Typically trucks have front or rear sumps where as cars have a center sump. Not a 100% accurate philosophy but a good place to start. Dipsticks are a pretty common loss dipstick tubes not so much.

This era of truck always had a front sump pan from the factory.

How do you know the 383 isn't original to the truck? They didn't have the VIN on them. In trucks they were used 67-71, so not many years.

I know it's not original because my truck was built in September of 69, the motor wasn't built til March of 70. On the bottom of the block the first part of the vin was stamped on, and that doesn't match the trucks vin
