Hi guys, after many hours of pouring over previous posts on this subject I still have a couple of questions. It is a given that I have to change all brackets, use a 351-400M bellhousing, and use my 390 flywheel.
However has anyone heard of making a 1/2" spacer to go between the block and bellhousing, what about the two different depths of bellhousings? Has anyone used the Hooker engine swap mounts PN#12677, they look like they use the OEM Ford cross bolt type mount. I will be doing this swap real soon, hopefully ths month as my 390 developed a hole in the oil pan due to a rod exiting the block.

I just did my 460 swap heres what I used.
1]stock 1979 351m bellhousing

2]390 flywheel

3]Mr Gasket flywheel bolts or auto trans flexplate bolts ]both have thinner head to clear disc]

4]Luk clutch set p.n. 07-050 [fits 77-82 400m 12"]
Note this is a brand new not remain clutch it has to be a diaphram type clutch. Every remain 400 dia. I ordered came as a 3 finger type they are to long. You could use any 400m clutch aslong as it is the dia. type and it has to be from a 400 to bolt in the existing holes on flywheel.

I used these peices with no spacers [other than factory] and the pilot bushing that came in the set. I made no modifications to bushing or the bellhousing. It fit like a charm no clearance problems no binding etc.

As for motor mounts I used advanced adaptors which worked great. But I already had the 351 frame perches Im not sure if they make then for the 390.

Good Luck Andy feel free to ask anything else

 

Yes living in Canada really sux if you are a motor head. Not only is our dollar worthless, we aso have a mountain of taxes to pay (14.5% on parts). Let alone if I want anything rare to sell up here AKA LandL mounts and any related items I must also pay brokerage fees, duty fees, taxes, and of course the exchange rate. So now you see why I am exploring my every option, and measuring twice and bolting once. Mind you the quality of beer here is excellent Thanks for the replies. I think I will look into alternate sourses for the LandL mounts, they look like my best bet if the stock Ford ones prove too weak.

 

Thanks for the great info Andy. I have been told so many different stories from people who have never done this swap, it's nice to get some accurate info from someone who has . Anyways looks like I have to turf my 360 flywheel and look for a 390 flywheel to fit the 12" diaphragm style clutch. I will do some measuring of bellhousing depths and related clearances just to me sure that everything bolts up kosher (call me ****)I take it I also need to change the bell crank that bolts to the block.
By the way, have you or anyone else on this forum looked in the engine swap frame mounts offered by Hooker?

Check it out from Summit:

Looks like it uses the stock ford cross bolt mount, and bolts to the side of the frame rail. If I am correct, the frame width of my truck is the same as all years (73-79) so these should work on my truck.
One again thanks for all your help Andy and any others with some input.

 

I used the same bellcrank that came with the truck yours may work. Dont turf your flywheel yet. I beleive the 360 flywheel has multiple clutch mounting holes and 1 set should line up with this clutch combo you may have to tap the holes and the crank bolt pattern is the same.Or a good machine shop could redrill the flywheel cheaper than buying a new one. I paid 30bucks for mine from the bonyard and another 20 to resurface. Im just saying check what you have before you buy.

Good Luck you will be thrilled with the power when your done Andy

 

I just checked those mounts out. I had the same ones and sold them in favor of what i have. Heres the deal with them you still need the rubber engine mounts for a 460 which you can get from any parts store. You also need the shells that bolt to the block from a lincoln engine. If you have cool if you dont. You will need to hunt them down since they are obsolete from the dealer. You may want to look into l&l mounts it maybe more cost effective to just buy theres than all the peices needed to use the hooker mounts. The mounts I used wont fit your 74. But if you already have the rubber mounts and shells the hookers should work good. I got my 460 from a 77 150 4x4 someone junked so it already had the hooker setup. It didnt appear it would bolt to my 250 frame as easily as the 150 frame so I got different mounts. Sorry to ramble on just wanted to give you all the help I could.

 

I looked in to the LandL online, and they look like they would work if I bought some frame stands from a 351-400M truck. However my local supplier wants $300 for them (note that I live in B.C. Canada). The Hooker ones are $200. I E-mailed the Hooker tech dept. to see exactly what mounts I need.
I guess I will have to wait and see
I will post the reply from hooker as soon as i get it.

 

wow thats alot if you change the frame perches you could use the advanced adaptor monts also. I have to look on monday in my catoluge at work. I know paw hjas those hooker mounts for 79 or 89 us dollars which would still be cheaper. I will post or email you monday about what I found.

 

If you plan to mod the 429 even a little or use it it hard go for the L&L mounts. I kept breaking stock F250 mounts in my '82 Bronco/460, and they're no fun to change, until I went with the L&Ls. They've been in there for about 10 years through two engine changes and a lot of hard use.

 

Before you buy LandL, check out Performance Unlimited and their "Stealth Mount" motor mounts. I just bought a set and they are a lot cheaper than LandL. Also, the Stealth Mounts are a far better, more durable design with only one draw back: the motor mount stud holes must be relocated 2" closer to the front of the mount tower. I took my two towers off and drilled the holes-no big deal. I am in the final stages of my 400 to 460 conversion in my '78 F-150 4x4 so I may be able to help you some.

 

I know some subscribers on other boards have car club affiliations that let them ship products from the US to Canada on a personal basis to avoid some of the taxes in a commercial shipment. Maybe you could find a Canadian FTE clubmember who could arrange that.

 

I have installed 460's in 351m/400 360/390 trucks with the use of 2 5" sq. x 1/2" thk plates. Drilled the mounting holes from the pattern of the old 460 mount and then weld a 1/2" x3/4" bolt to the back side. You will have solid mounts but there cheap and won't break.

 

So will an FE engine mount up to the same tranny pattern as the 385 series engines?:-X11

 

[updated:LAST EDITED ON 02-Jul-02 AT 02:01 AM (EST)]460 and 351M/400 all have the same bolt pattern on the back of the engine where the bellhousing bolts upto and when I did a manual tranny swap in my 77 350 that was 460 powered I used the 360/390 flywheel and spacer plate etc. The clutch I used wasn't a 12" it was a standard 11" used behind all the Ford truck engines only the 460 engine used in 1986 and newer trucks had the 12" clutch and a true 460 bellhousing and flywheel. I never could get a 12" clutch to fit on a 390 flywheel some of them used a 11.5" clutch but they only come in rebuilt versions not made anymore new.

I never had a 11" clutch slip on me with the 460 and I used to gross the GVW of the old 77 to 12 to 13 thousand pounds carrying gravel on the deck. It was a SWB flatdeck dually and I used to work the truck hard and the 4spd was a well worth it swap for me I hate juicer trannies.


I'am too a B.C.er and finding old 70s trucks nowwadays is getting hard the salt used on the roads here during the winter has rusted them away to nothing. I would love to have a old 79 LWB dually flatdeck again but those trucks are pretty rare I was considering of putting a 79 Cab on a F-Superduty chassis or even a newer F-350 4x4 chassis and put a 12 foot dumping flatdeck on it.
