the thermostat housing is in the front. and all i am saying is that everyone who has looked at it said they thought it was a 351 cleveland. but it is a 400 cubic inch motor.

 

But really; what can you tell from LOOKING at an engine? If I were to tell you what my engine was, just by looking, I would say it was a small Chevy, distributer in the back, Chevy style exhaust. But, it's a Ford 292 Y-block.
If you only post some casting #'s, then we can tell you for sure. If you KNOW it's a 400cid, then it's probably a 400M, the only 400 (I think) Ford ever made. And from reading these posts, then this would look pretty much like the Cleveland engines...
Some of these engine gurus can probably tell you what it is by the description I asked for earlier...and sorry if I wasn't clear, but they would need to know where the thermostat housing is in comparison to the water pump.
So, to tell for sure, we would need some casting numbers, a very detailed description, or someone might be able to tell you what you have by what kind of car it came out of.

Sorry if I came off sounding rude, sometimes my fingers go faster than my mind :-)

Andrew,

I wouldn't worry about sounding rude. After all you are trying to help this guy, and he's the one that's not listening to what you guys are asking him for.

OK! YOure 400 is going to Look Like a CLEVELAND BECAUSE ITS EXACTLY THE SAME>>I TOLD YOU THE DIFFERENCES!!
THATS IT>..TRUST ME I"M NOT FULL OF SH#T
thats why everyone thinks it looks like a cleveland cause it is.
IT IS MOSTLY DIFFERENT INTERNALLY EXCEPT THE DECK HEIGHT


390GT aka Brent.
unless its a GT its just a hunk of iron

 

Ok, the motor is about 30 years old, it has about 250,000 miles on it, it leaks oil, about a quart a day, i will just let all of you help someone else, i was at school earlier when i put the other post, there was no way i was gonna beable to answer all of the questions, and all of the numbers are no there, i got a good answer from another site, so dont worry about the crap anymore, i am rebuilding another 400m and i was just wondering how much hp it might be running, so whatever.

Later

 

'71 9:1comp 260HP@4400 400ft-lbs@2200 (these are gross HP ratings)
'72 8.5:1comp 172nHP@4000 298ft-lbs@2200 (here and below are all net HP ratings)
'73 8:1comp 168nHP@3600 314ft-lbs@2000
'73 8:1comp 171nHP@3600 314ft-lbs@2000
'74 8:1comp 170nHP@3400 330ft-lbs@2000
'75 8:1comp 144nHP@3600 255ft-lbs@2200 (California emmisions)
'75 8:1comp 158nHP@3400 276ft-lbs@2000

that is all i needed

 

Look man,

Everybody here was trying to help you, and you just went ballistic. You never said you were rebuilding another 400. If you would have said that I am sure these guys could have told you. But there is no need to go off and throw a temper tantrum about it.

Well, I wouldn't expect him back anytime soon, but, for everyone else; If you are coming here to ask for help, then you have to post the information that is asked for. Otherwise, you will not be able to recieve feasible information.
We cannot help you if you won't accept the help that is being offered...Remember, YOU ASKED. Don't ask a question and then come back all hot-headed and closed-minded. We can't help you if you don't help us.

Enough ranting for now,

BJ, it looks to me like you asked a fair question. I do think that there is some confusion with the terms used. If you had asked How much horse power does the 351/400 run, I think you would have gotten a different, and quicker answer. As explained before there are three engines in this conversation. the 351C, 351M, & 351/400. The 351M is a takeoff of the 351C but is not that engine. The 351/400 is a 351M block build.

You will find that generaly we try hard to help folks that come seeking it. Most of the guys here are really knowledgeable about trucks, and I hope this introduction to our family doesn't cause you to want to drive a chevy.

Hey guys,
Didn't sound like you were picking on him, you have to give to get. A little descriptive info would have allowed ya'all to be on the money with the proper answer. Ah well juveniles, I have a house full of them. I can't understand the ones I have. He needs to finish school and maybe he will have a new attitude.
Keep up the good work all.......

seems to me like he answered the question you guys were asking right off, he said he knew it had 400ci, and it loked like a 351 cleveland, I could tell it was a 400M from a car pretty easily

 

1975 351m 148-150 400 143-158 1976 351m 152 400 180 1977 351m 161 400 168-173 1978 145-153 400 160-167

 

WEll, sorry that i am 16 and i dont know crap about motors, all i asked is how much horsepower a 351m or 400m ran. Well i tried to answer all of you questions, but when 5 different people ask different questions, then i cant answer them all, and i wasnt throwing a fit, just trying to let you all know.. And i didnt think yall needed to know that i was rebuilding an engin, and if i knew everything about motors i wouldnt have asked that first questions. But i have to go, Sorry guys.

 

Sorry for Sounding mean.
anyhoo if you read some previous posts about your engine, the 400 or the 351m you'll get the same thing..dont bother wasting your time on it....go with a 460 in it.
Youre truck may seem pretty powerful because they do produce torque but you'll find once youve gotten behind the wheel of a truck with a 460 it makes the 400 seem pretty weak...Ive driven both..i just got rid of my 85 3/4ton with a 460
i could pull the @$$ end off of a 400.
but thats my opinion..and ppl on here know how i feel about the 351m/400's.

 

[font size="1" color="#FF0000"]LAST EDITED ON 17-Dec-00 AT 02:56 AM (EST)[/font][p]Hey 78Orange:

Boy you sure caused a ruckus when you asked how much horse power a 400 has. That's nothin'. A while ago a fella asked what FE meant and you should have seen the heat over that one.

Stick around here, there are a lot of experienced guys that know what they are talken about (and some that just talk).

As far as your 400. As you can tell the answer to your simple horsepower question can be very complicated. Your perception of engine horsepower can be affected by many factors ie; gear ratio, type of trans and its gear ratio, GVW, tire size and many other things.

I drove one stock, and one not so stock, 400m engines for a total of 500k. They were dependable and served me very very well, however I decided my next one would be 460, but that's me. Whatever YOU decide to do keep us posted, that's how we ALL learn.

Especially if you can figure out how to make a 400 or 351,
M,
C,
FE,
CID,
XYZ,
high thermostat,
low thermostat,
tall or short valve covers with 8 or ten bolts
and 4 or 6 fan blades


REALLY WORK FOR THE MONEY,
I for one would be impressed and interested.
