How do you tell a 302 from a 351w and a 351m?

The simple difference between the 302 and 351w is simply deck height. The 351w is taller. They share a majority of interchanging components. Both the 302 and the 351w have a water cooled intake meaning a water bypass hose between the water pump and intake. The 351m would have an aircooled intake meaning no bypass hose. Also the head design of a 351m would make the engine look a lot larger (wider) than the 302/351w


Is the bolt pattern the same for a 351M and 351W?

No, the 351m has a big block bolt pattern, and the 351w has a small block pattern, this caused some what of a problem for me seeing as I had 5 spd tranny off a 351w that I wanted to put on my 351m.


What motors in a crown Victorian 351w or 351m?

351m (modified) were last made in about 1980 to 83... 351c (clevelands) were last made in about the same time. the police interceptors had a 351w with a card on it.


Can you use the same transmission on a 351w and 351m?

No not if you plan on using the same bell housing.


What does the 351 stand for?

In automotive terms, the 351C, 351W and the 351M were V8 engines produced by Ford. They had a displacement of 351 cubic inches.


Will a c6 fitted to a 460ci fit a 351ci?

Yes as long as it is a 351M, 351C and 351W use the smaller bellhousing pattern (same as 302).


How do you tell the difference in the 351w and the 351c?

There are different ways. One is that the 351w fuel pump bolts to the timing cover,the 351c bolts to the engine block. Water flows through the 351w intake manifold and does not on the 351c. The 351w has inline valves and the 351c has canted valves. The 351w has squared intake ports and the 351c has huge round ports. Hope this helps some.

How do you tell the difference between the 351w and the 351c?

The way I tell the difference is the engine thermostat location : On the Cleveland it is mounted horizontally by the distributor and on the Windsor the thermostat is mounted vertically in the end of the intake manifold


Is the Ford V8 351 a small block or big block?

It depends. There is a 351 Windsor, a small block, a 351 Cleveland, a small block, and a 351 Modified, which is a strange mix of big and small block features. These are referred to as 351W, 351C, and 351M, respectively. The 351W looks just like a 302, only it's a couple inches wider. The 351C has a smaller block than a 351W, but much wider cylinder heads than the 351W. The 351C was offered in both 2 barrel and 4 barrel versions. The 2 b heads had ports a bit bigger than the 302/351W, but the 4b heads had HUGE ports. The Cleveland, although it's quite wide, is still very much a small block. (the block isn't much bigger than a 302's block) And then the 351M.. I refer to these as 351"Mutant", even though the M really means "Modified". This strange 351 has a hellhousing pattern and engine mounts that are interchangeable with 429/460 big blocks, but heads very similar to 351C 2barrel. The block itself is roughly the same dimensions as a 351W. It's more small block than big block, but a lot of guys refer to it as a medium block. Whatever. I just call them Mutants. And there you have it. A real quick way to check is to look at the number of bolts holding down the valve cover. Eight indicates 351C or 351M, Six indicates 351W. Also, 351W valve covers are flat and have a rectangular profile, while 351C and 351M usually have a trapezoidal profile. They never offered the 351C in a truck in the US, only the 351M/(and 400 - a stroked version of the 351M)


What kind of engine is in an 78 f250 ranger?

all big blocks , 351m,400m, 460 and I think the 351w. I'm sure of the smaller ones 351 and 400's as I've had trucks with them.


Which is a better motor a 351m or a 351c or 351w?

They are all good engines but the m is not a powerful engine. The 351c code R is considered by most to be the most powerful but there were low power models built which was Code H. The 351W is an entirely different engine than the 351C even though they are the same size.
