1974 Ford F250 Highboy 2015 Chevy 5.3, 6 Speed Auto Conversion
Hi all, I'm new to this forum but not new to ford trucks. I learned to drive in my 74 ford and it's been in the family longer than I have! I will post pictures soon but I have done a complete restoration on the outside in candy apple red, and recently the 360 seems to be running on 7 cylinders and blowing oil. I am hoping to do a modern 5.0 coyote engine and manual trans swap in it. I have done similar swaps with chevy efi engines that have gone very well, but this will be my first ford engine swap. I will surely have questions, but will post pictures and info to help others who are thinking about doing the same thing.

Welcome! I like seeing old trucks stay in the family. Like you, I inherited my dad's '77 Highboy and am also wanting to do a Coyote swap, but with an auto. Seems very straight forward since Ford offers all of the electrical components necessary to swap them in. Just pricey!! Keep us posted with your progress!

Here are some pictures through the last decade. the truck use to be a teal color, but I went with house of kolor red. In order to make the restoration quicker, I purchased a parts truck from eastern washington (less water, less rust) and restored that body off of the truck, painted it off the truck, and then transferred the body parts on in a weekend. Since then, I moved to las vegas for three years and sitting in the sun killed the paint so it was repainted in the same red about 4 months ago.

Here are a few more pics of earlier this year, right after paint. I put in a new bed liner, weatherstripping, tail lights and a few other things at the same time. A week after these were taken, I drove the truck 1,100 miles up to washington state towing a car on a tow dolly! about ran the whole west coast out of gas lol

Still doing research on the 5.0 stuff. Here are a few things I've learned and a few questions maybe people on here can help with.
Tuning the factory computers for standalone can not be done with HP tuners but can be done via mail order tuning for not too much money
A ZF6 manual should bolt up behind a 2011+ 5.0 but am not certain about the input shaft and crankshaft mating up and the bearing that goes there. this would also allow me to use a manual shift transfer case
I know later model dana 44 front axles that came from these generation of trucks have disc brakes and are a direct bolt in replacement, but are there other newer years of f250's this would work with too? like an 80's f250? would like disc brakes.
From what I understand a Bronco II gas tank will fit between the 4wd frame rails, as they are narrower than 2wd. I look forward to getting the gas tank out of the cab!
Also, the only option for a power steering pump for a 5.0 that I have found, that keeps the air conditioning pump is a very overpriced March kit. however, the 6.2L engine comes factory with a power steering pump. I would much rather a 5.0 but this is tempting.
Any input is welcomed!

Also... everyone here is going to hate me but this happened. I penciled out the 5.0 swap and the costs of getting power steering, standalone tuning, etc etc and it was close to 6 to 7 thousand me doing all the work. Or a 2015 5.3 and 6 speed auto with very low miles is around half of that.....

Maybe you can find a good EFI 460. My buddy had a 1990something E350 with one, but junked it when the transmission failed.
I'd rather keep Ford architecture under the hood, but I'd still rather attempt to put LS heads on a 335 series engine (351C, 351M, or 400) than put in the whole LS engine.
I think folks have put LS heads on small block Fords, and I know that 335 series heads can be surprisingly easily made to work on Ford small blocks. (Boss 302)
