I've got a 351M in my '53 out of a 1976 Gran Torino car. The exhaust manifold on the driver side is all one cast piece with a cone type connector that bolts right up to the ex. pipe by way of a ring. The other side manifold is different in that it has a cast "donut" that is flat on the end that bolts to that manifold's flat face, and has the cone on the other end. It's like an adapter, but it came off the Torino just as it was from the factory, I assume. Someone told me it was the heat riser valve but I see no valve aspect to it at all, it is just a smooth bored "donut". One of the ears bolt hole is broken and I'd rather not use it. I have found a 1977 truck 351M ex. manifold on line that doesn't have this donut but instead had the cone cast right in it just like the driver's side one I have. The guy wants $60.00 for it and $20.00 to ship it which seems pretty high. Well, I guess I'm willing to pay it but I want to be REAL sure it will work. But how much difference could there be? Sorry for such a long story. Thanks for any insights, JNB

 

Maybe if you could provide a pic we would better see what the problem is. I'm having a problem with finding a passenger side manifold that tucks in better than the truck manifold myself. (middle pic is a truck manifold) Here's some pics that maybe you can match it up with. What you don't see in the truck manifold pic is how much it flares outward from front to back. I can go take pics of mine in a while.

 

Looking at this picture, there's not much difference between yours and the truck manifold, but I would assume there is a difference if there are casting number differences. The truck manifold is D7TE9430AB

 

Thanks Havi, I'm not savy enough to know how to post pictures on here yet. The part number that I am considering buying is: D7TE9438-AB460 from a guy in Canada which could be throwing a wrench in the gears. I'm not at home right now but later I can get the numbers off the manifold I'm talking about. None of the pictures you have on here look familiar to me but I don't recall ever seeing a truck manifold for this engine.

 

Wait, I take what I said back, the drivers side manifold pic looks just like the one from my '76 351M. Is the problem your having got something to do with the starter? You said you manifold is too long at the back?

 

I just went and looked at my '76 Torino 351W, and it has the same middle piece you are referring to. It is merely a middle piece AFAIK. The 351W Torino manifold I have angles the outlet down more than my 351M truck manifold does. And that may pose as a clearance problem to the frame.

EDIT: My issue is I have a big bell C4 behind my 400 going into my '87 Tbird. The 351C slip tube headers I have don't clear, and so I went to try manifolds. The driver side will clear with a borgeson steering shaft, the passenger side flares out too much to hit the side of the engine bay, the starter would be an issue, too. So my search is for a cheap set of 351M/400 Torino or late 70's Tbird manifolds. The first pics I posted are from 351C in early 70's Mustangs, and that looks to clear my bay the best, but the odds of finding a set for real cheap is not likely. I just don't have the funds to go searching.

 

Havi, I'm confused, but then that's not unusual, not at all. (After a while, it becomes a way of life). In the first three pics that are together you said the center pic is a truck manifold, but that looks just like the later pic you show in your second post that says 1975-78 Torino/Cougar right side under it. I'm not sure what AFAIK is.(?) I'm curious about what slip tube headers are, as well. If you go on ebay motors and type in 351M ex. manifolds, two different people have truck manifolds with different numbers, one from Canada being the number I gave in my earlier post the other guy shows the number you gave me. That one sounds more correct but it is kind of confusing. I'll get the number off the passenger side manifold this evening when I get home. Jay

 

AFAIK=As far as I know.

Casting number itself never changes. Only the revisions do (the later letters, such as AB) Pass. side manifold is 9430. I didn't make clear, the truck manifold and the Torino manifold for the pass. side look the same. The camera angle fails to show the outward angle they make, and that might be the difference between the two. The 351C 2v and 4v head design, as far as exhaust manifold bolt holes are concerned, are the same as any 351M and 400 regardless of vehicle, car or truck. Therefore they will all look the same to some extent, and that includes the exhaust manifolds as well. Your pass. side manifold and the truck manifold could look a lot alike, but there will be differences, as the D7TE prefix shows it was the casting design as 1977. Obviously later than 1976.

Slip tube headers are simply 4 tubes from the head which are separately fastened and "slip" into a collector.

 

Okay I got it now but you gave me an idea maybe I should go one ebay and look under 351C exhaust manifolds for what I want. Thanks again!

 

I'm not sure if you tried, but you might search your local wrecking yards for a manifold. They may have a bunch of them laying around, and since those engines have been out of production for 30 years, you might find a deal on one. It's worth a shot before sending $80 to Canada.

 

I have a 400 in my 78 Bronco. I also had picked up a 400 out of a early 70's car. The passinger manifolds definitely are different and the truck manifold might work in place of the car one as it points down more as in Havi's picture. One caution on the 351m/400 manifolds is that the passenger side is prone to cracking. I have one of each laying in the iron pile that is cracked. I'd let someone have either for shipping, but you would have to find someone to repair the cracks.

 

Hi Husker, It looks like you're just right up the river from me. Nice to hear from you. Here is my situation, I am not opposed to using the manifold I have, it is in good shape but the "donut" I discussed it broken on one ear. It is useable but I like to have a good one if I could find one. Do you know what I'm talking about and would you have one? That would be great! Jay

 

I'll take another look at what I have. I think I know what you mean.

Also, if you haven't checked it out, we have an active Kansas FTE chapter. Check out the state chapter forums and pop in and introduce yourself. It would be great if you could attend one of our gatherings.

 

If you find one I'd really like to have it. Interesting that you would suggest the Kansas Chapter of FTE, you know, I've already applied for membership. Do you have a regular e-mail address I could have? Thanks Del!
