351M Ideas

Did the guy get run off the site?

LOL, ya right. He doesn't do message boards. This guy is WAY old skewl.

I believe a friend of mine has an aluminum 4V intake for an M block.

The one that was stock was a cast iron unit low rise DP for 2V heads. Weiand and Edelbrock make aluminum DP for 2v cleveland style heads.

Heh heh - - I also have never seen a 400 with a 4-V carb, either! I think I have that book laying around at home somewhere . . . I'll see if I can dig it up and the reference to it you mentioned.

I know there isn't anything listed in the Encyclopedia of American Cars regarding a 400 with a 4-V carb for any of the years up through 1975 . . . if there is such an animal (either a 400M that came with a smallblock bolt pattern, or one that came with a 4-V carb), I'd sure like to see it!

I saw one back in the 70's sittting on the floor of a Junkyard engine room. Didn't know it was rare at the time.

Block 400 FMX - Clevelands Forever!

There's a photo of a 400 FMX block with the small block bellhousing bolt pattern.

I also wouldn't put a 400 in a Mustang, but if you were building a 400 right now, I'd bet you could get some reasonably priced performance internals from some of the people who won and placed high in this year's Engine Masters competition.

Edit: regarding the 4 barrel carb for a 400, on the same wiki site linked above they have photos of a 4 barrel factory intake for a 400.

Got a link to the 400 4v intake? I looked but came up empty handed.

 

[D.Hearne]

Nevermind, I found it. The one I saw would have been an earlier casting as it was the mid 70's when I saw it.

You KNOW it's an oddball when it has SK and XE on it rather than normal Ford numbers.

Actually, I think that the XE means it's an experimental part . . .

That's correct, and SK stands for sketch from what I've read. That's what I'm saying, you know the part is rare when it has those letters!

FWIW:

Also FWIW: (it's a Fox, I know, somehow, I thought my old page link went to the fox swaparoo page, sorry)

 

[D.Hearne]

Did you notice the regular engineering number under the XE ?

 

[havi]

yes, 1977. A bit later than 1971 or 2. Perhaps with the 351M/400 going into the '77-79 generation of Tbirds it was tried out?

 

[D.Hearne]

Nope, it was meant for the LTD's with an A in the prefix. But would have and could have also been used in other lines as well.

Sounds good to me.

Im trying to find some info. I have a c4 that was told came out of a ltd or something. Called ford and a local tranny shop they said numbers match for a 64-72 c4 it has a "big block" bell housing. I dont need it. Dont plan on using it. Would like to sell it. Whats it worth. I know they are rare. But how rare and what they worth?

I had a 2 barrel 400M in a 1978 Bronco. I think FoMoCo put it wherever they had a heavy vehicle to move.

 

[Edster]

Maybe you could make a trade for a small block. Too big for an early Mustang. But putting a small block in place of a six is not without its challenges. Frame mounts, motor mounts, throttle linkage, rear end, driveshaft, trans, possible trans mount too. I did a Falcon years ago. Yes the parts are available but it did cost some dough.

Its been a while so I don't remember the dimensions. Is the M bigger than the C?
