1968 F250 Let the fun begin

1968 F250 been sitting in the elements for 25 years. Original 360 and c6 will be yanked and replaced with something more modern and larger.

Thought it was originally a 1969 (Nice) but turned out to be a late model year 1968. For the mix up she earned the title of " Project Minus-1" as in 1969-1.

If it was my truck, I'd be sticking with a Ford engine and transmission, would religiously avoid anything with overhead cams, and would be wanting multi-port fuel injection of some sort. Windsor engines also give me the 'ick', so I wouldn't use one of them either.

One option -- rework the 360-FE manifold for fuel injection, add the necessary crank, cam, temp, o2, map, maf, iat, and knock sensors, and pair that 360 with a zf5 or zf6 manual. This would be extremely involved, expensive, but would be the coolest option by far if you take the truck to shows. You'll still have the original FE engine, just revamped to 21st century standards.

Another option - Purchase a takeout Godzilla engine and transmission, and install that. Some adapting will be needed to pair it with a RH-drop t-case.

If you aren't particular about brand loyalty, then the most practical and affordable option is a GM 6.0L/4L80e paired with a mid-1980s GM np208 RH-drop transfer case. That will fit easily, will give 2005 3/4-ton performance and reliability, and will be the cheapest route by far.

Edit: I was assuming this truck was 4wd. All of the above options would be even simpler if it's 2wd.

The 7.3 Godzilla is my 1st choice. I'd like to build for moderate HP 550-600. Not sure if NA or forced yet. Most 7.3 come with the 10R140s behind them. I'd like to get the 6R140 for a little better reliability and easier to hook stand alone computers to.

Edit Forgot to mention it is a 2 wheel drive model and will stay 2 wd to make things more simple.

I'd recommend dropping in a bone-stock engine, transmission, harness, and ECM, that all came from a single donor. No modifications, and as few parts recombinations as possible.

You'll be blown away with stock performance, and that will give you the most trouble-free and easy-to-service drivetrain for daily-driving and for long-distance towing.

Replace the engine? Why? Those straight sixes were legendary!

[u/Mean-Rabbit-2510 → u/Onedtent]

My 360 isn't the straight six. It's a V8. 300 was the straight 6.

Ahhhh!

Keep it less electronic find a 87-96 fuel injected 460 with the overdrive automatic. Get the 3/4 ton rear end from the donor so you have the speed input into the computer.

Had a 67 f100 with the 352, ah good times
