Which oil pan for Dart block?

You will be able to use the stock type t/c and oil pump and water pump. Just make sure you use a true double roller chain set up. Cloyes, Ford racing are good examples. Also use a good oil pump Melling Ford racing and get the heavy duty oil pump driveshaft. Water pumps, there are quite a few good company's out there, just get a nice high flow type preferably a aluminum one.
