Searched and searched and no luck what I actually need.

Ive got a 66 f100, short box R/c. Ive got a 351w, and I need motor mounts. But Id like to keep the c4 in the spot its in right now on the original trans mount. Question is, I know what motor mounts will fit, but how far back/forward/no movement, will happen when I do this? Id like to know so I can make one round trip to my machine shop if I have to have the drive shaft lengthened/shortened.

Also, has anyone done a 351w/c4 in a 66 eff series, and ran long tube headers? If so, how was driver side clearance around the steering shaft?

Ive been doing this for a long time, no stupid smart *** answers.

 

Any 289/302/251 truck motor mount will work from 1966 to 1986. Right and left are same. You need to get the correct motor mount perches. They will be from a 2WD 1966-1979 F-series truck with 289/302/251. These are common in wrecking yards. I usually find a later 70's model to get them.

It makes more sense to move trans crossmember forward than to move motor around to fit the C4 where the old trans was. If that is what you are referring.

 

I was trying to not have to modify the driveshaft but if I have to I w'll. Yards around here do not have many ore 80s ford, so i will have to buy new.

If it's possibLe I'd like to know how much length the driveshaft will need to have added on

I can custom fit the trans member.

 

Your perches will have to come from 1966-1979 only. Frame went thru major changes in 1980. The motor mounts are cheap and available at any parts house. I may still have a set of perches. They would likely be lost in my surplus of parts, but may be able to find them....eventually. I can measure the driveshaft on my `65 stepside. It has a 351C and C4. Length should be spot on. But I would wait until motor and trans is fitted before cutting anything.

 

If you could that would be awesome. I am restoring a step side too.

I won't cut till I know for sure but it'd be nice to send my guy measuremen's so he knows a relative ball park work load.

Long tube. So you run them? If so do they clear steering shaft?

 

Gee whiz, where did you get this info from? It's flawed!

No truck came with a 289, 302 first installed in 1969 F100, 351M/400 first installed in 1977 F100/350, 351W first installed in 1981 F150/350.

Same engine supports aka towers/perches/stands = 1969/79 F100 302 - 1975/79 F150 302 - 1977/79 351M/400 2WD

1980 and later perches/rubber insulators will not work!

 

OEM part numbers may have changed over the years with some major improvements, but parts are interchangeable for the years listed.

The mounts fit these motors

289/302/351W (rubber insulator)

66-86 Bronco
E-100/200/300 69-74
F-100/150 69-86

Anchor 2329
DEA A2329
Pioneer 602329

87-96 Bronco F-series

Anchor 2564
DEA A2564
Pioneer 602564

The 87-96 motor mount (rubber insulator) is much beefier, but still interchangeable with the earlier ones.

Early mounts were just two plates with vulcanized rubber
If broken motor would lift up and tear up the fan shroud.

Newer ones were pinned between the plates
Help prevent motor from lifting

Late model are heavily reinforced
Almost impossible to break apart if rubber separates

I own a 67 Bronco289, 77 Bronco302, 79 F100/302, 81 F150/351W, 88 Bronco/351, and 94 Bronco302. Also a 74 E100/302. The motor mounts are all directly interchangeable.


The perches are a direct bolt in for 1965/79 2wd trucks. When chasing parts in the bone yards, it is very common to see engine swaps with correct perches already installed in earlier trucks. I have removed plenty of parts from earlier model trucks that others have already done swaps on. If searching for used parts, dont pass up looking under the hood of an earlier model truck. It may already have everything you want.


I was not aware the 77-79 351M/400 shared the same perches as the Windsor motors. The ones I remember look more like what fits the 460.
Its been 15 years since I was deep into swapping everything around.

My apologies for any misinformation.

 

351W's were only installed in 1969/89 FoMoCo Passenger Cars & 1975/97 Econolines. F150/350 & Bronco didn't get the 351W until 1981.

*New completely revamped Econoline introduced in February 1968, but Ford called them 1969's.

 

Being as 1966 trucks never came with a 302 or 351, your crossmember will not have all the holes in it matching the holes in the Windsor/M pedestals. So, if you mock up the motor with your trans attached, you can drill the holes where they need to be to locate your trans EXACTLY where it is now (front to back), thus negating the need to make any modifications to your driveshaft.

Really. This is just awesome. Thanks for that as my driveshaft and rear end has already been installed to an almost perfect angle. So I am assuming they still make these engine stands? And where is the best place to buy? Not any junkyards here with them lying around.

 

The pedestals (or perches, if you like), have been obsolete for awhile, so wrecking yards, you-pull-it yards, ads for parts trucks in the buy & sell, etc.
I actually just pulled a set last Sat, and under really *****ty conditions.....and the engine/trans was (and still is) in the truck

Well, looks like Im going to fabricate my own. I know for a fact there are none around here for 150 miles that have a pre 85 Ford. Fabrication is easy peasy though.

 

Oh c'mon! You don't have craigslist where you live

I can't imagine there isn't a viable donor listed in parts section of Craigslist somewhere near you....

I guess you could always give Tom @ Flashback F100's a call, he should have some, he's in NC.

Autofab makes a bunch of different mounts and perches that will fit our trucks. They're certainly more expensive than the junkyard but an option none the less. They look like they could be solid mounts, so be aware of that.
