Who all has done this? I want personal experiences. I want to swap out my 4.9l to a 460.
Currently have 1979 f250 4x4 300-6 np435, np205.
I want to have 460, C6, np205.
Questions
Do I need anything special to bolt c6 to np205 if I pick up any old c6?
Do I really need L&L or Advanced adapters for the engine mounts?
I have read I need a bodylift to do this swap?
I want to get a junk donor truck with 351m/400 c6 np 205, if I find one with np203 do I need to find a different c6 tailshaft?
Any info is greatly appreciated!

If you can find a donor 74-79 w/ 460, then you can use the OEM style 460 mounts. Their design is much different than the mounts used on any other engine.

From the donor you'll need the pair of frame-to-mount brackets, and the pair of mount-to-block brackets. You can then buy new OEM style mounts to sandwitch between these brackets.

I'm in the process of swapping a 460 in place of a 351M in a 1980 F-250 2WD I checked LandL prices and found that dealer parts were cheaper. LandL claims theirs are stronger but I'm driving on the street and couldn't care less about strength. Unlike chevys you'll need a lot of extra parts to put a car motor into a truck. Try to get a truck 460 it will save you about $200.

 

I just completed the same swap your doing only it was in a 76 F150. I can't help you with the trans / t-case questions as I ended up keeping the stock NP435 / NP205 combination. I did purchase the rubber motor mounts from L and L for a couple of reasons. First they do have a lifetime warranty which is good. I don't go off roading or racing with my truck but I still like things with warranty's. Second I got those mounts because the only mounts I could find at parts stores, and I checked a lot of stores, were for 2 wheels drives with 460s. You will also need the V8 frame perches. I believe I used a set from a Bronco that had a 351M in it. In fact I'm sure of that now because I also used the Bronco's bellhousing. One thing you will have to do is take a measurement from you bellhousing to the block. This is needed because I had to move my frame perches back (towards the cab) as you can not use the same bolt holes as the 300 I6 frame perches. You will need a rear sump oil pan so that you will clear the front axel. I used one off of a Ford van that had a 429 in it. I also did put a 4 inch suspension lift in my truck just for added protection. If you are going to do any off-roading I would recommend at least the 4 inch lift and taller bump stops on the axels. You will also need a bigger radiator as the 6 cylinder one will not cut it. I put in the biggest radiator Ford made for the trucks. Its a 4 core with dimensions of 24 1/2 inches high by 26 1/2 wide. Use the stock 7 blade fan with a good fan clutch. I looked at going with electric fans but after talking with several companies they all recommended going with the factory setup. My motor is running about 500 horsepower so they didn't think there electric fans could cool it adequately. For exhaust I would recommend the L and L ultra flow headers with fender well exit. They were real easy to work with and I have heard nothing but good things about them from the guys in my area who have them on their mud racing trucks. Also you will need the power steering and alternator brackets. I lucked out and found a truck in the bone yard with the brackets still on it. Hope some of this helps.

 

Thanks guys,
Good info!
I haven't checked yet if the f250 and f150 frames are the same.
I do have a f150 to compare to. The good thing is I found two big old broncos for parts (engine perches trannies steering column...) Just need to know if all the half ton stuff will work on the f250. But hey I guess anything is possible with wome drilling torch and welder right!

[font size="1" color="#FF0000"]LAST EDITED ON 10-Oct-01 AT 09:53 PM (EST)[/font][p]4fords, Did you use an externally balanced 460. What did you have to do to setup the clutch and bellhousing assembly?

 

[font size="1" color="#FF0000"]LAST EDITED ON 11-Oct-01 AT 02:30 PM (EST)[/font][p]I am in the process of doing a similar swap.. Pulling the 460 and C-6 tranny our a 75 mercury marquis and dropping it into my 73 F-250 3/4 ton 4x4 with 360/np435.. I have been doing alot of research and if I'm not mistaken all that needs to be done is changing the motor and transmission mounts. Besides the obvious, I know I am gonna have to modify the Driveline from the transfer case to trasmission and make my own mount for the transfer case shifter... If I am mistaken someone let me know. Also, After looking in some parts catalogs I have found the motor mounts and tranny mounts for my exact year to use the 460 and C-6 without modifying anything...

 

Just to point something out, there is no difference between a 'truck 460' and a 'car 460' they are the same block. They do have different motor mounts. Good luck with your swap, but I want to know, why are you pulling the 300-6?

Really, I have been told otherwise by several people that the motor mounts on the car will not work on a truck.. I know that there is no difference between the motors themselves. But have been told that I must change the motor mounts to put it in my truck.. and I sure hope I have room.. I may have to tear out the inner fenders for it to work.. Have a feeling the valve covers may rub against them.. Have a 360 in it now and the valve cover is only 6 inches from the inner fender.. Like I have said this is no ordinary truck.. I know your picturing a 73 Ford under the hood.. But you must picture a 49 under the hood.. Anyway, I know I didnt start this topic but have been learning alot by coming to these boards. thanks.

have you thought of just using a motor plate setup? If its a total custom job already, maybe you might be better off with either making your own plate, or making your own mounts. Do you have to lower the engine to fit in your body or raise it?

I don't have to do anything as for raising or lifting it already has a 6 inch lift. I already have a motor with a rear sump oil pan.. And the 460 I have has the rear sump pan as well.. As far as I know so far in researchign this a little bit. .IS I just need to change the motor mounts and possibly the transmission mount. As well as having the driveline modified and making my own bracket for the trasnfer case shifter. There is alot more work that I will be doing before dropping it in as well.. I have to weld in a new floorboard and rewire it as well.. One project at a time I guess..

you wlll need the frame mounts,motor mounts and engine brackets. Also for the 80 and up frame you need a oil filter adapter, stock or aftermarket. Contact FPX at 423 332 3837 they have everything you need. Jake

 

One of the Ford books claims the 1977 (D7TE) 460 truck came with 4 bolt mains. There was one of these blocks on Ebay last year.

[font size="1" color="#FF0000"]LAST EDITED ON 13-Oct-01 AT 11:52 AM (EST)[/font][p]I'm pretty sure that Ford never put a 460 in its trucks in the late 70's. To the best of my knowledge the largest displacement motor you could get then was a 400. Furthermore, I'm sure that 460's never came with 4-bolt mains. The only motor from the 385-series that did was the 429 CJ & SCJ (I'm not 100% sure on that). 85351HO, was it both that the CJ & SCJ that 4-bolt mains, or just one of them?

On an extension of what I said earlier, I stated that there was no difference between a truck 460 and a car 460. I was talking about the block and dimensions. Of course motor mounts will be different because of the diffent sub-frame design.
