Pictures 351c, 351w
K. iv'e heard of all the differences between the 2 styles of motor's but have never seen the real differences, alot of what people say about these motors is kinda confusing and i would like to see the front of the two motor along with the veiw of the top of the motors so that i can actually see the difference, i have tried to find these pictures on google and having wasted 2 hours searching have failed to find any. So in my request, i have been offered a screamin deal on a 351c. but want to make sure it is a 351c. can anyone please assist me with some pictures, i would highly appreciate it, thanks in advance.

hi the cleveland will have a dry intake. the top radiator hose will go into a waterneck on top of the block, whereas a windsor has the top radiator hose going into the front of the intake manifold{like a 302} the heads on a cleveland will have a 2 or a 4 cast into the top corners of the heads. the heads with the 2 casting will be better for low end power.parts for the cleveland are not as plentiful, but they can be found. i dont have any pics, but its pretty easy to tell the difference. greg

a 351 W will look like this
http://i41.photobucket.com/albums/e2...sport/351w.jpg
and a 351 C will look like this
http://i41.photobucket.com/albums/e2...sport/351m.jpg
now for the fun part. the picture is of a 351M. the M and C engines look alike, but the M engine uses a bell housing bolt pattern shared with the 351M, 400, 429, and 460.
the C engine, has a bell housing pattern of the 6 bolt 289-302-351W engines.

Once you see a few 351C then a few 351W, you will never forget the difference. The 351W just looks smaller, but the water neck is the dead giveaway. If it's in the intake manifold, it's a W.
The 351C and 351M/400 problem is solved in the width of the intake manifold. The M block is clearly wider, but that is your only real clue to see the difference by eye.
Also, the heads with the 4 cast in the corners, if you see those, you may as well just give them to me and try to find yourself the "2" cast heads... ;P

BTW, you will find the 2 and the 4 on the upper corner of the head, right past the end of the valve cover. The M motors typically do not have anything cast there, however that is not a guarantee, things get changed around alot.
A windsor will have the thermostat located in the intake manifold. A 351 will have it in the block, facing up.
Another thing not mentioned, a 351 looks exactly like a 302. You can tell the difference by the width of the intake manifold, and the 351 has ribs above the top two belhousing bolts. Here is a good pic. The intake gasket is even with the dizzy mountin g bolts on a 302, and is about 1/2" higher on a W. Measure about 10.5" across the intake manifold
Count the valve cover bolts
2 bolts the engine is a: 239/256/272/292/312 (produced from 1954 to 1964 Y-block)
4 bolts = Fuelie 460
5 bolts the engine is a: 332/352/360/361/390/391/406/410/427/428/ (FE engine)
6 bolts the engine is a: 221/260/289/302/351W (Windsor family)
7 bolts the engine is a: 370/429/429/460 (385 sereis)
8 bolts the engine is a: 351C/351M/400 (Cleveland / Modified 335 series)
Beware of the industrial motors(shown in RED. 361, 391, 370 and 429's bear a resemblance to their FE and 385 series counter parts, but are not high revers, and require $$$ to get good power out of them

The 391 FT was also used as a service replacement for the 428 because it could be bored to 4.13, as it was cast with thicker walls. Sometimes recognized by a reverse "105" cast into the front of the block just below the driver side head. I had one of these in my 1974 F100.
As for "And you have a race car of some sorts that you are going to put those heads on? "
You don't need a 'race car' to put these heads on. My 1971 Torino GT came stock with the 4V quench heads (M code) 11:1 compression, and went like hell. No, I wouldn't have gone down to a 2V on that car. That thing screamed lke a banshee in stock form.

It could smoke the tire(s) up to 3rd if I kept my foot in it... And ya know what? That was with 2.75 gears... Still stock, so why go with a higher ratio gear if it could do that?
And if you really want to know, my old car is fine, in the hands of a friend who bought it from me, because I got a major back injury at work and had to sell my pride and joy to feed my family; But hey, thanks for asking!
