"a little frame trimming"... not so sure I like those words, but it can be done.

 

Here is a video of a nice 79 4x4 with a Coyote in it. This is one of 3 I have found on the interweb. There was a crewcab on ebay recently with one also.

This swap is not cheap. I don't care who you are or whether you start with a donor truck or use scrap-yard parts--you aren't getting this running and driving for under $10k.

Also, someone mentioned adapting the newer transmission to the old 79 transfer case--- why? The new transfer cases in the 2011+ F-150's can withstand 1000 horsepower. So swap in the motor/trans/transfer case all from the same vehicle.

The Gen 2 Coyote's (2015-17) are 385hp/385tq.... by the way.

 

I just wanted to mention that there is indeed already an adapter for the 6r80 to NP205 (also one for the Bronco Dana 20 which is what I would do).

Personally Instead of an E4OD or Gear Vendors OD behind my 400, I will probably just swap in the 6r80 + Bronco Dana 20 (but will look into the stock F150 transfercase) as that sets me up to drop a Coyote in at some point down the road when my 400 gets tired.

 

How will you bolt 6R80 to the 400?

$550.00 american for an adapter???? Uhm... yeah... no...

Would love a 6-speed behind my 400, but $550.00 is pretty steep for some sort of adapter plate.

 

I didn't think $550 was out of line. Don't forget you also need $1000 worth of computer control and a trans cooler and custom driveshafts.

A 6r80 behind my 460?.. sounds sweet.

 

Can you just imagine the reduction in RPM's at freeway cruising speeds?
No more "drone" sounds from exhaust.
Instant MPG increase.
Win-Win.

 

I really think swapping to a 6r80 (or a ZF5 for the manual guys out there) is a cost effective job. I think it will become more common. The driveability and all-around enjoyment of the truck would be soooo much higher. You would probably have to drive around 50k miles to recoup the money spent with gas savings.

The ability to keep low (4.10) gears, the ability to talk in the cab while going 85mph on the freeway, no fluid leaks, more gears for towing, better use of the power of the big block, the fuel mileage, the acceleration... I'm sure there is more I'm not thinking of.

I recently watched a video of a 2017 F-150 with a lift and 33" tires run a 13.8 second 1/4 mile. Truck had exhaust, intake and tune (Coyote). That is really fast for a truck! And that was with the stock gears -- which most F-150s have 3.31 gears unless you specifically option up to 3.55. Think about a 93-95 Ford Lighning or 454SS of same vintage -- those trucks couldn't break into the 14's!! Now I know we don't really care about drag racing a Highboy 4x4, but the point is the new F-150 is mostly able to do that BECAUSE of the transmission. The Lightning had what basically amounts to stock big block power (250hp/380tq) and an E4OD and 4.10 gears. The 6R80 is that much better, and costs roughly the same amount to swap into a Pre-79 truck.

Not to highjack this thread, as there are plenty others talking about Coyotes... I've already started my swap.
