Since you already have the Cleveland I would rebuild it. It is actually a very sought after engine. Any 4x4 c6 will work the 2wd version will not work.

 

thats what i hear, is there a vin on the motor that i could easily find to make sure the guy i got it from wasnt full of crap? or any other way to make sure its a real 351c? he was very convincing though. i just dont know much about them. i assume the tranny is original to the truck.

 

on the Cleveland the part where the fuel pump goes in is cast as part of the block it is not a seperate timing chain cover like the windsor. here is a link to some pics of a Cleveland http://www.flickr.com/photos/7137611@N05/3463648689/

 

that "looks" just like mine.

 

If it really has the 4v Cleveland heads swap them out for the '70 to 73 2v heads, They will give you much better low end torque.

 

Post a couple pictures of the motor. If it's a motor out of another vehicle a VIN check won't do anything at all for you.

 

Just my .02:
I'd sell the cleveland (if thats what it turns out to be) and put in the 400. Its a better truck motor stock and you should get some good cash for the 351 c for upgrades.

 

But if it is the cleveland, the 400 won't bolt up to his tranny. 351C is small block bell housing, 400 is big block bell housing :thumbup

So he'd have to replace both if he went this route.

 

well it is deffinately not a small block. it probably is the 351 c. it looks about the same as my buddys 400, i didnt measure the intake though . what i was wondering is if its a 351 m and the guy just told me its a cleveland. maybe the engine and tranny have been replaced with a 351 m or hell, maybe its a 400. the guy seemed pretty sure telling me it came from a 70 torino. i dont really care what motor i have as long as it just goes..lol. is the c6 hard to rebuild myself? a rebuild kit is just 100 bucks on ebay. i have rebuilt manual tranny's but never an auto. i may just bebuild the trans and hook everything back up for now as long as it dont smoke too bad. i just need it for this winter(i live in the smoky mountains in tennessee). i'll get pics of the motor on here tomorrow if i can

 

well it is deffinately not a small block. it probably is the 351M.

Fixed :thumbup

 

The tailshafts are actually different on the 4x2 and 4x4 trannys. Yoke vs. splined shaft. And thats the first part in the case, or last one to take out of there...

Is it a Cleveland? A 351 Cleveland has 8 bolt valve covers vs 6 on the Windsor's and the themostat is mounted vertically in the block vs. the intake manifold on a Windsor motor. I have not been around enough 351M's to know if they have 8 bolt valve covers but it is my understanding that Clevelands are the only one. Assuming the valve cover is off, a Cleveland will have "porcupine" or canted valves (staggered valve springs).

If your cleveland is a 4V model IMO those heads have no business being on a truck, they are to much head. Ports you can put your fist in. As stated earlier the 2v heads would be a great truck head.

If you find your motor is a 70 4V cleveland with the factory Autolite 4bbl and intake/heads, exhaust manifolds ect... Be aware that that a original untouched motor has some value in the Mustang/Torino/Cougar/Ranchero restoration world. You may be able to sell it to the guys that care about that motor and build something that is a better fit for an 82 Bko.

 

351c/351m/400 all use the same heads. you have a 351m unless someone swapped it in, which I highly doubt.

 

sorry, if you had read the top, the guy i bought it from told me the engine was from a 1970 torino and the truck came with a windsor. its not a modified. i have narrowed it down to a 1970 351 c. now im just trying to figure out if the it has the boss heads or the cobra jet heads.

 

I've been trying to find external differences between 351c & 351m motors. I have read that on an M engine there is a vertical ridge on top of the block, next to the distributor, behind the water pump, that is not supposed to be there on a Cleveland. Some describe it as a fin. I don't have a Cleveland to compare it to, but can see it plain as day on my 351m. Does your engine have this ridge?

You can see it below the distributor in this pic.

 

supposed to be a cleveland here.

I don't see that same ridge on it. That may be an easy indicator.

 

my friends mustang fox drag car's 351c does not have a ridge on his block by the dizzy. (previuse owner swapped it in)

 

That amazingly bright blue motor is a 351c, I just finished building one last year {and its on Ford Muscle.com} and own -5- 351c motors.

 

If the heads have the "4" cast on the corner they are indeed 4V Cleveland heads and are definetely different from "M' heads. Mucho bigger ports & valves, & flow way more air. Like has been said, not good for low end torque, but sought after for high RPM racing engines. Casting #'s for Cleveland block-D0AE-D-two bolt mains-DOAE-C is four bolt mains. Casting #'s for 4V heads-DOAE-G, H,M,N,R-D1AE-GA, D1ZE-DA is CJ head, D1ZE-B is BOSS 351, D2ZE-A HO, & D3ZE-AA is another CJ head. Each series of head has different size valves & chambers. Which engine you have will determine it's value. If it is an untouched original & complete 4V, 4 bolt it should be worth considerable $$. Good luck.

 

Agree with CS79. The "4" seals the deal.

What makes the heads keepers is if they have closed chambers. I do not know which casting number is which. The Quench chambers are best for making power and not pinging.

An easy indicator is the distance between the edge of the water pump and the deck of the block. The taller deck is the 351/400M.

Whether to rebuild or not depends on your intended use. 351C do not make a lot of torque, but they also moved those Torinos around fairly well....

look into making the valvetrain adjustable as this is a real limitation on these motors if you swap the cam.

If it is torque you want and are willing to swap a tranny, a 460 is the cheapest solution.

 

ill try get some pics up

 

no ridge here

 

here is the 4 on the head
