You've got coolant in your engine oil. You've cracked the block / or cylinder head / or head gasket. That is a virtual death sentence to an engine. You need to get a new engine

If you rarely drive more than a few miles at a time, so the engine is constantly running cold, it can be normal (except the oil leak, of course). In that case the coolant is not disappearing (you don't mention coolant loss), or is disappearing for another reason. Gasoline produces right at a gallon of water for every gallon of gas burned and it is inevitable some of that water will end up in the oil. If the engine is not regularly heated enough to boil the water off it makes the stuff you see. Some people are shocked to see their oil level drop a quart in a couple hours of freeway driving - the water is boiled off. Anyway, if coolant is not disappearing that is what is happening... guaranteed. But you need to find the leak. The best clue is the part of the engine compartment the puddle is forming under. Newspaper under the car is a good way to get that figured out, then go from there.

sounds like you may either have a warped head or a gasket problem either way that is your coolant leaking into your engine oil making it look milky. you must have overheated it pretty bad before. i would be willing to bet you were driving down the road one day and it got really hot and the car started to slow down and no matter how hard you pressed the gas it just kept on slowing down. you probably warped the top part of your motor. lot of money to get that fixed. good luck

The head gasket is leaking. Possibly because the head bolts weren't tighted down properly. Drain the oil and get the head gasket replaced before you drive that truck anywhere.

You have a leak between the oiling and cooling system. Could be a head gasket, cylinder head or crankcase. Hope it's only a head gasket.

Your cylinder head is cracked. Coolant mixing with the oil causes that milky looking stuff. Sorry

either a leaking head gasket or a cracked head or block. Pull the heads and check your gasket real close for any tracking signs.

Chances are very good that if your engine was re-built that your heads could be cracked. Most later model 350 heads are too thin (to save weight) to endure rebuilding and need to be replaced instead of re-built. Are you blowing smoke out the tailpipe???

you have a bad head gasket, replace the head gaskets and change the oil and filter and refill the anti-freeze and you should be good to go.
