What is the difference between 351w and 351m

Joined: Sep Difference Between W and M? Hey Folks, Have an interesting question for you all. What is the difference between a W and M, only difference I can see is the distributor. Buying a and gentleman is telling me that it is a W private party want to make sure I know exactly what I am looking at before I purchase.

Any help would be fantastic!! Find all posts by 74bronc Find all threads started by 74bronc. Find all posts by 73stallion Find all threads started by 73stallion. When I bought mine the guy it was W I assumed it was too, came home ran some numbers and it is indeed a C.

It doesn't matter whats on the outside, it's what's under the hood that counts. Madgyver's Garage Firebronco Yellow ClassicBroncos on the rock My builds. Click links below for pics. The Windsor W was introduced in and stayed in use until The Cleveland C was first used in on some early-production models, and was last produced in , when it was replaced with the Modified M model.

The first number on the VIN code on your Cougar designates it a model year, and the last letter, "M," designates it a four-barrel carbureted engine. There are several external differences that can help to distinguish between the W engine and the C and M engines: The W has three bolts attaching the valve covers on the exhaust manifold side; the C,M has four. The W has the timing cover bolted to the block. The timing cover on the C,M is cast as part of the block. On the W the thermostat housing is attached to the intake manifold, on the C,M it's attached to the front cover.

The fuel pump attaching bolts are mounted in the horizontal plane on the W and the in vertical plane on the C,M. Will the Cleveland fit my Lincoln Town Car? Lets not forget the Cleveland was used by several other companies, most notably Detmasa in the Pantera…. Told it had the highest compression ratio of a Ford engine. We were doing road rallies in the NE. Needed Boss front spoiler to keep front wheels on the ground.

Too much back story…. Clevelands have two fuel pump bolts one on top and one on the bottom. How do I know? I own one in a 71 stand. So I guess a couple of you just like to flap your gums. He bought that truck new but cursed the engine every time he had to drop down into second gear with his foot through the floor going up a extra steep hill.

It was a pretty gutless engine for a truck that size and definitely not much of a highway cruiser. Amazingly the truck still exists today but currently has a in it. Bought an F custom, with a heavy service bed and crane brand new with the m 2V in Had the same problem having to downshift to get up hills. One supposed remedy to poor mileage during the gas crunch was high gears so the engine was turning slower at 70 MPH.

Unfortunately, I had to use the granny gear to start out, or waste the clutch. Put a high-flow eldelbrock intake and Carter 4 barrel on it with an RV cam and felt like it doubled the HP. Had it running in 3 days. Hauled that heavy truck around like it was nothing but still had the way-too-high gear problem on long, steep inclines.

On the flat however, the high gears let that truck run over mph in 4th gear! Not that I did it very often. Still have the truck today with the 5th or 6th motor in it. Went back to the 2V with better heads and the thing has good power and … gets 14 MPG … remarkable when you consider the 11, Lb. I really liked your info on the I always been a huge fan of that motor.

I just had an opportunity to buy a good rebuilt c 2v. I have a 67 Mustang and put it in it. Is this true?

Thanks for you time. I have a 73 mustang the original c matching was stolen from my garage just wondering what you would think this would be valued at? Clevo and M engines had some anomolies. Though buy FM pistons that are way down the hole and you will end up with about 7. Mine now has 60cc C [Australian] heads and gets 9. Why did Ford ever make them so large? I believe some aftermarket W blocks use Clevo size and they are too big as well. But a bit better.

The is suited too what it was installed as as a engine for 2 tonne tanks. Mine is a 71 LTD. Even the 2V intakes really are too big. A Performer gives them a Chev race port intake runner. The long rods give it so much low end torque it is hard to get off the line without frying [semislick race] tyres. It is in a budget road race car. I got a M in my F how can I tell what year it was made or they all the same in all the years. W hat years did the make them?

I have a f with, what I was told is a W. The distributor is wired to a firing order of Which is not the right firing order for a W. How can this be? Thank for any help. Howdy, Re. Hey Ricky, thanks for the heads up. I have several blocks. I need to know if there is any markings to go by l want to put a in my 78 f Advice and Comments? I checked some forum threads and the consensus seems to be around or so.

Radiator Hose. Windsor engines have the radiator hose and thermostat installed into the intake manifold, where it exits from the front of the engine.

Valve Covers. Due to the ability to handle more power, the C6 transmission was used in many Ford trucks with bigger engines, and in larger cars that were manufactured with bigger engines.

Windsor is a couple pounds heavier as well. A stock w truck lower has oval shaped ports, inline with each other, much like a Mustang lower. It will not work. Skip to content Miscellaneous.
