1965 F-350 4x4 Swap

My 1965 F-350 has the 352 stock engine, love it death, its as strong as can be
BUT theres a crack soemwhere, coolant is getting into the oil...so...
what do you guys think i should do for a drivetrain?
i got 3 options
1. i have access to a 1979 bronce drivetrain (351M,C-6,NP205 t-case,dana 44 front, and ford 9" rear)
2. i also can buy a 6.9 diesel for $400 to put in my '65, just need to get a transmission for it, and possilbly a rear end to handle the torque
or 3. I can buy an '88 F350 with the 7.3 diesel, whole truck for $500, i can take the drivetrain from that to put in my '65.
Of these three, the 4x4 bronco drivetrain is the most complete, i just have to find a manual tranmssion to bolt up, because i hate automatics
the two diesel options both would need transmissions and possibly a new rear end.
the stock rear end on my '65 is a dana 70...which i think can handle just about anything..
ok...what are your thoughts?

Could just be a head-gasket.
Has the engine been running ok prior to discovery of coolant in the oil?
Maybe you caught this early enough to be able to get away with a fairly simple repair?

yeah i'm thinking its a head gasket, i got a fair amount of oil seeping out of the head gasket and running down the front of the block...otherwise engine's been running fine...i'm just leaving myself an option to go to if the head gasket isn't the problem. my dad and i put Bar's Leak into the radiator so that it would seal up any leaks from coolant-to-oil...we'll see how it does.

Far and above the easiest and lest expensive is to repair or replace the FE. The 4X4 swap is very difficult and will take months to do.

If you do a 4X4 swap, the Bronco stuff is too light for your truck. It is not even as stout as what was used in the F100, and will not handle the weight and use of a F350 - IMHO. I would pass on the Bronco.

Either of the two diesels will work for you, if you want a diesel engine. You would have a better truck if you took your chassis (cab, fenders, and box) and mounted it on one of their frames.

It just sort of depends on what you want in the way of a truck.

Hey B.O.B.,

if you've got coolant in the oil, I don't think you want to be adding Bar's leak to the radiator and continue running the engine as your oil is contaminated (w/ coolant) and you'll do some ever-lasting damage to the engine (rings, bearings, etc).

Have you done a compression test yet to help determine the head-gasket issue?

Most FE engines came standard with a steel head gasket. From experience, most rebuilders switch over to the composition head gasket, (asbestos between two pieces of steel) to eliminate any chance the [resurfaced] heads have a slight amount of warpage. This also reduces the compression ratio a bit.

Before tossing that FE away..consider the head gasket as the most likely source of milky oil.
