I would like to put 460 into a 1967 f100. the"67 now has a 390 with ford 4 speed. I have the 460 mounts and purches but need a bell and clutch set up that will work. Can someone tell me what big block engine bell selection I have to draw on to get a bell that will work with the 460? Also, if a setup from something other than a 460 would work, would the flywheel also work with the 460 engine as the 460 has a flex plate on it now. Thamks...Ron

 

I have a 428 4 speed top loader set up in my 69. You need a beel from a 429 4 speed car. They came in Torinos and Mustangs. You'll need the flywheel also. This with a short tail 4 spped will work. Are you trying to use your stock 4 speed?? Is it a granny ??

Hey Fuzz, check this post https://www.ford-trucks.com/dcforum/DCForumID11/376.html it'll give you some very useful info. Just finished this swap in my rig using a late model (87, externally balanced) 460 Hope this helps..trey gorbett/ 78 F250-Bronco Hybrid "SuperBronco" 460,NP435,NP205,Dana60 front,Sterling 10.25 rear,4.10's, 17/40x16.5 GroundHawgs http://communities.msn.com/treys4x4

 

If your 460 is a '78 or older you can use the flywheel and clutch of your 390. You need a bellhousing from a 429-460 or 351M-400.I have done this on three trucks and had no problems.

You will need the longer 400 bellhousing to use the 390 stuff. It is for the three fingered pressure plate,where the short one is for the diaphram style presure plate.

Do you know were there are any more of those $100 lakewoods? I need one for my pulling truck and hate to pay the price of a new one.

 

Dennis, you seem knowledgable on these swaps, have you ever had the opportunity to compare the flywheels to the later externally balanced 40# flywheel? Just curious as even using the diaphragm clutch I found that the input shaft brg. cover on the Np435 contacted the clutch disc. Somebody told me that L&L used to make a spacer to space the bellhousing back for this swap but no longer offer it. Guess they'd rather sell a their own flywheel and clutch setup at $500 a pop! trey gorbett/ 78 F250-Bronco Hybrid "SuperBronco" 460,NP435,NP205,Dana60 front,Sterling 10.25 rear,4.10's, 17/40x16.5 GroundHawgs http://communities.msn.com/treys4x4

 

Dennis, I lucked up on this one here in Baytown at a friend that deals in used perf. parts, particulary Ford stuff. Only one he had, but you might check some of the mustang shops. Trey

 

Yep,its the stump pullin granny all right. It has C7T35-1 on the tag. Taking off in second is no problem with the 390 and I suspect the 460 with cam, porting and edelbrock performer and headers will be no problem either. I was at a junk yard today and spotted a big block series with the bell and 4 speed tranny on it lying right out in the open for easy pickings. Thing is I do not know if it is a 429 or 460 or 400 or what ever. The dipstick was located in front of driver side bank. But my 460 has it on drivers side. Mine came out of a motorhome. So who knows. Are you saying that the only setup that will work is from a 460 or a 429? Is there a sure fire way to call out a 460 and 429 other than chasing numbers? The yard man could not tell me what engine it is without looking at numbers. So basically,I am looking at a stick setup that has come out of a truck with the same tranny as I plan to use. But I do not know the the engine family that it is on. Thanks for your help

 

When I did my swap I first used the 400 bellhsg. and had to grind the casting on the sides where it dimpled in for the bolts because it interfered with the flywheel. Having got past that I found that the crank had been thrusted forward by the front trans cvr. contacting the splined hub of the disc. Trimmed 3/16" from that and restored the thrust (.008") but found the angle of the throw-out fork wasn't very good and might would cause some binding problems. At this point gave up and found the Lakewood while hunting the stock 460 bellhsg. .....Trey

 

I have a '79 460 in one truck that is ext. balanced.My'79 F-250 came out with a diaphram style but had a Borg Warner trany. I parted out a later'77 F-250 that had a NP-435 and it had a long style in it, so this may be true.Could the cover be shortened enough to make it work?

Dennis

 

be aware that the late 79 on up 460's are externally balanced and cannot use the 390 flywheels as the earlier 460s did. ..Trey

 

I haven't done much with 429/460 engines. I had one in a 70 Torino GT . The 351M/400 has a similar block, so some parts will swap. The bellhousing might work. Flywheels, youmust watch the balance. I found a few interesting things when swaping the Fe in my 69. The FE truck bellhousings are 7/16 deeper that a car bellhousing. When runninga 11 1/2 clutch/flywheel with an FE, you need the big bellhousing from a 428 or a 390 GT, with the bump in the bellhousing. Well, because of the depth, a factory truck bellhousing will clear the 11 1/2 flywheel. Because of the extra depth, a stock FE truck trans has a longer nose on the input much like a small block trans. Thisis taken care of by the deeper bellhousing. What this meant was that I could use a small block top loader, with the longer input. This was much easier to come up with. There is no difference in strength, as the big spline 1 5/16 top loader is the only one that is stronger. All this may have no bearing on your swap, but it should point out that there are many places for things to be off a little here or there. Basically, get the correct flywheel to keep your engine is balance.Get the bellhousing that will fit your block and clear your flywheel. The 429 engine used the same big spline transmission as the Fe in cars. This is very rare and expensive ( i have one in my 68 CJ Mustang). It is the short input type, just larger diameter. If the bellhousing you get needs the shorter input trans, you can easily grind some off if it is a problem, even if you try to stick with the same transmission, or opt for a 4 speed from a car.

Hey Dennis, I'm not sure on the bellhousings for the Long-style clutches, they might be the right length 6-7/16" is the stock depth for the 460. I tried one with the 400 bell and the pressure plate contacted the clutch fork pivot block even without the fork. The Haynes manual I have suggests that there are two different bellhousings.......Trey

 

I agree with Pete, just be careful with measuring your components and double-check your clearances. I've also heard that there are two diff. input shaft lengths but haven't seen em. I've got 3 NP435's (1975,1978) and they both measure6-1/2" from tip to the front case. Eric O'sullivan, who's running a big block Ford in this year's TTC, lost one engine when he did his swap to a clearance problem pushing the crank forward. I think he shortened the input shaft and cover...Trey
