The only other drawback to the 460 is the small agravation of putting them in the trucks. ie exaust manifolds or headers.. The frame needs cut to use ex. manifolds and there is not much room for headers. I personally do not like the outside the frame headers. Just my opinion though.

 

Now there is a man that has his head in the right state of mind.

orangeconv: it may be of some benifit to review a couple of the posts I have made about the project I am doing now. I have a 78 F100, converted to a 4X4 that I put the 400 in. I am in the process of replacing it with a 460. No fault of anyone, but the engine I have has problems, and a simple rebuild will take care of it, then I will be driving it.

A couple of problems I run into you may be prepared for is the Mounts, exhaust, and the Flexplate(flywheel). These are things I found different that people swore to me were the same. I should have come here first and researched it.

The flexplate is the biggest problem. The offset is different, but you mention you have a 400 with C6 and 460 with C6. Just keep them seperate is my advice.

The Exhaust was easy to cure, just took time and some welding. I did not run into any problems or clearence issues with the frame, but I used the manifolds and pipe, and stayed away form headers, and just over sized the pipe.

The Mounst on the other hand had to be completly altered. You will have to do some fabrication here unless you can adapt the ones from the other vehicle.

I would be interested in how it turns out for you.

 

I dont know about 460's from lincolns, but the 460 i have came from a truck and the exhaust fit just fine...i cut the original exhaust on my truck off before the tranny cross member, and had the salvage yard cut the pipes on the engine just behind the tranny crossmember, so when i installed the engine all the pipes rested on the crossmember and i just took it to a muffler shop, they cut all the pipes to match and welded them up.....

all you have to do is get the towers and engine mounts from a truck with a 460 and buy the rubber inner at a parts store and your good to go...EDIT: sorry i just reread the first post and seen its on a 4x4 so im probably wrong about all that...i know thats the way it was on my 2wd..

 

The hard part is finding a truck 460. That will make it easier.

 

NP, I should add also I was adapting the mounts into a 2X4 Frame. This is why I had to box the frame, but the offset from the frame was setup the same with spacers both before and after the change from 2X4 to 4X4. I can tell you this, I under estimated the frame stress the 460 would put on the frame both from torque and weight. When I first installed the 460, I did not box the frame, but I did plate it for additional strength. Almost right off when I just had to test the power of the 460 by pissing off the neighbors with all the smoke, the frame cracked. I then pulled the 460, boxed the frame, then put it back in.

In my Gallerie, I have a picture of before I boxed it. This picture is after I altered the Mounts. I split them and added two inches to lift, and an inch towards center on each side.

I'll throw in my 2 cents: I like the 400 over the 460. Everyone has a 460, but as you can see from some of the responses to this post, some people have never even heard of a Ford 400. I think that adds something to the vehicle. I'd rather have a "stock" engine in the truck with 90% of the power that a 460 can provide (stock as in it came as an engine option from the factory). I rebuilt a 400 in my 79 Bronco, and not having to fabricate mounts/exhaust was nice. As if I didn't have enough things to do to get it running!

 

Does the 460 have adjustable rocker arms, or does it have the non-adjustable like the 400?

 

stock rockers are non-adjustable.........but you have to have them in the right position to torque them down....

 

The only difference between a 70s vintage "truck" 460 and a "car" 460 is the exhaust manifolds. The 460 was originally developed specifically for the Lincoln which is why the casting codes have a V in them as in D0VE heads, etc. As far as being stock, the 400 certainly wasn't stock in a 1973 F series so it's already been butchered.

I'm a big fan of both engines but then anything over 400 cubes gets my blood going. I get a real kick out of watching some of these TV shows from other countries where they talk about "massive V8 engines" and then tell us it's a 302. But I digress.

The 400 is a big motor with a long stroke, longer than the 460 and will build torque lower in the RPM range than a 460. Built correctly it will run with a mildly built 460 for awhile until it runs out of RPMs. That said there is no replacement for displacement as another poster said and 60 extra cubes ain't nothing to sneeze at. If you're willing to spend the scratch you can build a 600 HP 460 without even stroking it. 500 HP is relatively easy to attain with 460. Even with all of the aftermarket parts that are now being built for the 335 series family (351C/M-400) IMO it'd take some serious massaging to make that kind of power with a 400 and even then it's need to be stroked to 430+ cubes.

 

I have no clue what the motor in my truck is but i know it is a 400 with a 2 barrel carb that sucks and I was told that it has a set of cleveland heads on it, the 460 I have it is out of a 78 or 79 1 ton van so yes it is a truck motor with the good rods..

 

I have a Lincoln 460 in my 77 F250 with 3.31 gears. It will pull 8000 lbs up hills all day without a problem. It will even gain speed going up hills. The only things that is bad about it is that it only runs on premium and I need to make sure gas stations are close by. 460's will pass up anything but a gas station. I filled it up a few times this summer for over a $115. OUCH.

 

I went with headers from L and L for my 460 conversion in my 79 crewcab 4x4. I did not cut the frame and more than ample room for the headers.

Only problem I had with the whole conversion was the power steering pump/bracket. What I found that was factory and looks great is a 75 Ford van 460 p.s pump and bracket. (The spam can type). I did put an Edlelbrack Aluminum manifold and carb. She is a big truck with a lot of guts. I like the 400's also but when you step into the 460 you feel it...

I had no problem with the below................

Car exhaust manifolds are 2.25 and tucks are 2.5. The truck will breath better. Another difference pointed out by others is the truck pass. side turns inward and down more so than the car pass. manifold so there is no need to cut the frame. I've done both.
