Is there anyone here who can help out with a 400 to 460 efi swap. I've read many posts but none are if any write ups of a complete engine swap. Just bits and pieces.

I don't actually have a bronco but instead a 78 f150 with 400 c6 np205.

I also have a donor vehicle which is a 89 f250 with 460efi and c6 as well.

From what I've read I should have most the parts I need for this swap other then motor mounts.

Has anyone here done it with some tips and suggestions for this swap?

Here is partial section of an article on a 351M/400 to 429/460 Motor Swap
 @ http://web.archive.org/web/20050228122329/http://www.angelfire.com:80/wv/fordbroncos/engine.html
For posterity, here is all that is left of the article because angelfire screwed up people's sites.
In this section I will discuss alot about swapping the 351M/400 to the bigger Ford motors 429/460. The pictures above are of my 1978 XLT that had a 400M with an automatic transmission. I bought a 1978 F-350 that had a 460 motor in it along with the T-18 4 speed manual transmission that swaps right into this 78 Bronco.​

The picture you see here above (which is dark...and i appologize for that) is an idea I came up with when installing the transmission by myself. I put my engine hoist through the passengers side of the cab and wrapped the straps around the transmission laying on the ground to raise it into position. This works out VERY well. When swapping a C-6 transmission to a T-18 manual...there are some changes in locations that need to be made in order for this swap to work correctly. FIRST: The transfer case has to be moved forward (toward the motor) 3.5 inches....don't worry about drilling new holes in the frame to mount it...Ford already did when they built these. SECOND: Since you've moved the transfer case forward, now you'll have to change both front and rear driveshafts. If you have a drive shaft specialty shop in your area, take your old ones to them and have them made to fit the new application with the new measurements. If your Bronco is a Canadian version, the yokes from the automatic setup will have to be changed. Canadian Broncos for some reason have larger yokes on the U-joints than American versions. I appologize for lack of updating this site...and I promise to have alot more helpful info on this page as soon as i get more pics and more work done to complete this swap. I'll even post the exact cost down to the penny as to how much it cost ."

429/460 Installation 

Source: by Paul et al at http://www.projectbronco.com/Technic...ical_index.htm
read more articles:
significant excerpt; "Transmissions -- As far as the tranny goes, the 429/460 will bolt right up to your Bronco's stock transmission bell housing, however, there are a couple of things that may give you some problems you need to be aware of. First, some of the 429/460s used a different input shaft than the one that the Bronco 351M/400 uses. In this case, you are going to have find the correct torque converter/shaft combination that will work or have a custom shaft made for your swap. Second, the the 429/460 used two different types of flywheels -- one for the automatic transmissions and one for the manual transmissions. You need to make ABSOLUTELY sure that you are using the correct flywheel with your Bronco's engine and transmission! One other word of caution -- DO NOT try to reuse your 351M/400 flywheel with a 429/460 engine. Do what ever you like with it (make it into a clock, throw it at someone you don't like, or whatever) just don't reuse it! The 351M/400 flywheel will bolt right up to the 460, but all 429/460 engines are balanced differently than the "M" engines so the "M" flywheel simply will not work. Also keep in mind that the '79 and up 460 engines are balanced differently than the 78 and older 460s so be ABSOLUTELY sure to buy the correct year flywheel for your engine."

Yo,

Atomic EFI in a 79 is awesome by mattgunguy;
"...Brand spanking new351m crate motor.
Did a Msd Atomic EFI swap, Msd 8580 Billet distributor, FiTech 40003 fuel command center. Mild cam. Wrapped headers. Has maybe 5 minutes run time so far. 
The Atomic efi setup is awesome. Simply amazing throttle response. It is mostly a plug and play system. Between the efi setup, 6al box, and pro-billet distributor. I had maybe a few hours into install and wiring. The fuel system is more involved. I skipped that and used the Fitech fuel command center. 
 
I am having some fuel starvation issues. I believe it's the mechanical pump not being up to the task. I plan on getting something better before long.
 
Rolling on 35's. Looking to do either a AOD or a E4OD with a stand alone controller trans swap before much longer..."

EFI Swap Comprehensive Article

Excerpts;
"...Fuel Injection, some  are asking “why  again?”   Well, because  many  are still intimidated by  all this new technology  or don’t understand the  advantages.  So  to  get  everyone up to  speed, we are about to  start one of the  largest  series  of  EFI articles ever published in  a  magazine.  There is  so  much  to write about  and space is limited  in Bronco Driver, so I can’t fit  it all in one issue.   This will  not be  one EFI article  thrown together just for the  sake of stating “we’ve covered it.”   The Bronco Driver staff and I have a desire to give  you the absolute best.  So our goals for the next few  months will be as follows: Explain some  fundamentals of how it works Plan a fuel injection swap for the best results Swap an EFI 302 into a 1966-77 Bronco Swap an EFI 460 into a 1978-79 Bronco Upgrade a stock EFI engine for more performance Answer important questions along the way The goal to  accomplish in  this  article is to bring as  many people  as possible up  to the  same  level of  understanding.   To avoid answering answer a  thousand  help letters, I’m  going to  start at the beginning  like we should. Why fuel injection, and why Ford’s  fuel injection?   I can’t answer that without starting debates and holy  wars, but  you still deserve  a real answer.  A  stock  1970  Bronco 302 is  rated at 140HP/233ft/lbs; while  a  1990  Mustang 5.0L is rated 215HP/285ft/lbs.  Ford EFI  can  be had  at 1/3 the cost of aftermarket EFI systems.  Peace of  mind: not  many  fathers  buy undependable cars for their daughters, so why  should you drive one?   Ford is leading other  manufacturers in EFI technology development; they  spent  millions upon  millions of  dollars  making sure this  was the ideal  system.   No other  system  in its  class  has its capabilities.  It  can operate upside-down, even if  your oil pump can’t.  It will  never suffer from  vapor lock.  Hundreds of aftermarket venders have products  available for Ford’s EFI, an..."

Hey thanks... So since I cannot use my existing flywheel and torque converter do you know if I will be able to use the flywhe and torque converter from my donor? Or is there a different torque converter and flywheel I should be looking for? Thanks

Yo,

Sorry, missed seeing your last question due to error messages and lag I have in this site.

I don't know, but a yard that uses the Hollander Interchange System, manuals, etc can probably provide that info. 

"The Hollander Interchange lists interchanges or comparable part options for almost every car or light truck on the road. This remarkable resource tells you which OEM parts from one vehicle fit or "interchange with" another vehicle. Use the Hollander Interchange to broaden your part options, find less costly alternatives, and pocket the savings.

GL!
