Okay, I went over to the engine swap section and didn't get a reply. Tryin to do it right ya know. I'm home now on the 73-79 forum hoping to get a fairly quick reply. Gotta go to the wrecking yard here soon to look at some merchandise.
I found a wrecking yard that is claiming that they have a 460 bellhousing for a manual trans. I understand that I can use a 351M or 400 bellhousing and 390 flywheel, yadda yadda, for my upcoming engine swap but I do want to use the 460 flywheel that I have and a stock 460 clutch kit when installing this set up.
Question: can anyone tell me how to determine the difference between the 429/460 bell housing and the 351M/400 bellhousing? I am under the impression that the bellhousings are different lengths. Unsure, but if I am correct I need to know the difference so I know what clutch to buy, and also if I need a different flywheel.
If I am mistaken, and there is no difference, then please let me know that I am doing more work than I need to do. I'm prolly gonna leave here soon to go to town (1 hour away from home in the boonies) so I would appreciate all the help I can get to reduce my trips to town. I have heard that the Manual trans 460 bellhousings are rare finds. Please set me straight as I am also picking up my rebuilt 460 to drop into my baby tomorrow.

Thanks, Tim

 

no difference.
use the 460 flywheel and clutch. the stock 351M/400 linkage should work.

 

But will the stock flywheel and clutch work with a 351M/400 bellhousing. I believe that there is a difference in the overall length in the 429/460 and 351M/400 bellhousings. Am I wrong??? Question, is there enough room in a 351M/400 bellhousing for a 460 clutch and 460 flywheel???
Thanks, Tim

 

Okay, I just did some research and spoke with a pretty sharp Ford Fan and found that the 351M, 400, 429 and 460 bells are the same exact thing. Therefore, I don't understand why I keep reading on this forum that you need a spacer. What I am gathering is that if you use the diaphram clutch, you dont need a spacer.

 

i've been told there's two size flywheels for a 460.if you have a big flywheel (heavy truck) and a small bell (car & lt truck) the engine won't turn

 

go to L& L and buy the 460 429 flywheel and clutch kit,400 bellhousing and run it. that what i did and never gave me any trouble.
just make sure you dont go get a heavy industrial bell housing out of a 2 ton orbigger truck they are different. bad thing about using a 360 390 flywheel is there are smaller and you have drill the starter holes bigger, to get the starter to contact the flywheel. when trying to start.

 

Off the subject, but I like the "No I don't grow potatoes" thing, Fordfury

 

If you used a 360/390 flywheel on a 429/460 would'nt that throw the balance of the motor off as well? Should'nt you stick with the flywheel that came with the respective motor for balancing purposes.

 

my freind has been using one for years, on his 429 and 460, i think its dumb to use one for a 360 each time he gets a starter he has to modify the thing to work,his is an older engine. even when you buy one for a 460 they are not balanced, unless you balance everything.

 

That is why I said respective motor, it keep's it all in balance.

 

i agree with you 100 % i would think it would, i hate when people just throw stuff together with the wrong parts.

 

When I did my 514 I had to get the flywheel from motorsport for the newer balance as the old 460's were zero balance. I also got the bellhousing from lakewood. I bought a x/s torque starter.

This didn't work well in the sence that the starter would barely engage the flywheel and shaved it some and wouldn't engage at all. I had to drill the starter holes and shave the ring off the starter for it to work.

The problem was in the flywheel size compared to a 'stock' flywheel. Think the part was a -460z in the motorsport catalog. But this flywheel is only for the 'newer' 460's that have to be balanced. (think 12.5 balance)

I think you'll be fine on your stuff as long you stay with truck parts but not sure how easy a 460 car straight drive bellhousing would be to find so don't think you'll have a problem with that. Also I think the newer 460 straights were hydralic (sp) clutch so stay away from them.

 

I know this post was like 16 years ago, hope some of you guys are still around.
I'm taking a 400 out of an F250 with a 4 speed. I'm putting it in a lifted F100 with a C-6, and going to sell that one.
I have a 429 (D1VE block) that is hooked to a C-6. Not sure what it's out of. I'm putting the 429 with the stock 4-speed in the '78, and keeping that one.
I've been told that the engine mounts will need to follow with the engines, and otherwise I may only need a new clutch for the 78 for between the 429 and 4speed.
Sounds like if I'm reading some of these other posts right, the bellhousing may be different from cars to trucks, or maybe that's only real heavy trucks?
I know the D1VE blocks were used in 429s in country squire wagons and in 460s in Lincolns too, and I'm sure a lot of other stuff. not sure if the code was different for trucks, or if that 460/C-6 pairing was more universal.

is there something I can look for or measure on the trucks as they are, that can tell me the rest of the story, before taking them apart, to see if I need a certain bell housing or other things?

Thanks!

 

The bigger 460 flywheel should have a 12 inch clutch. It's been many years since I have messed with this swap but I do know I had used the 390 flywheel on more than one occasion. These swaps were in 78/79 4x4 trucks/broncos. I do not recall the starter ever being an issue but I can not remember which starter I used. The early 460 and 390 engines were neutrally balanced. If memory serves me correctly the larger 460 bell housing has a hump near the top to clear the 12 inch clutch??? It doesn't matter what block you have, only if you have a newer 460 that is not zero imbalanced then you need the matching flywheel for that setup.
