351 Cleveland, am I screwed??

[Sled182]

I have a '74 Cougar XR-7 with the 351 Cleveland engine in it, and I am tring to give it some more power by replaceing the 2barrel carb, intake manifold, cylindar heads, and headers. I cannot find any parts online for the Cleveland engine, only for the Windsor? Can any of you guys help me out? Thanks alot.

Have you tried looking in Jegs or Summit Racing? If still nothing buy a PAW catalog for $5. It's about the size of a phone book, but it's a parts catalog.

No you can get some HP out of that Stinking Ford Motor. Replacing the intake manifold and adding a 4 barrel carb will help. Jegs and Summit will do you lots of good.

This is a great motor
you can find all kinds of parts for the 351 if you look under cars like the Pantera there are allot Pantera sites on the internet and there will be plenty of people with used parts also
don't give up on that Motor
if you have trouble finding parts email me we work on lots of Pantera at my shop

I'd make sure you have a 351 Cleveland. If the engine matches the car I bet you have a 351M. which is a cleveland family motor but does have some differences from a 351Cleveland. One of which is throwing on a 4 barrel intake and carb do dick to it performance wise sadly

[Scott 02]

What the hell is with all the 351 names? I have seen 351m 351c 351w. Whats the deal? Yes, Id make sure you have a 351c, I would make sure I didn't in that situaton b/c im not into fords all that much, but what I have heard in the past.....The 351"c" is right for you.

351Winsdor, Cleveland and Modified explained. The names and where they came from actually make sense once you know everything. I'll try to give you a good short answer cause writing it all is a pain.

351Windsor: The name windsor comes from the windsor family of ford motors. The windsors are ford small blocks. 289,302,351. What makes a 351W a 351 and not a 302 is increased stroked but no bore increase. So the deck hieght of the motor is raised. Since mostly all parts are interchangable in this family, All those 5.0 parts can go on a 351W.

351Cleveland: Once agian name is gotten from the Cleveland series blocks. The 351C is actually a big block. They 351C was predominantly put in performance cars. It has 4V quenched heads and 4barrel carbs stock.

351M: The M=modified. Ford started making a 400 based on the cleveland family. But do to emission lawss etc.., What Ford did is they destroked the 400 to 351 hence the name modified. The differences between the 400,351m and 351C. The 400/351m have a larger main journal diameter. Due to there use in passenger cars/trucks they have torque making 2V open heads and came with 2 barrel carbs. Do to the head design just putting a 4barrel intake/4barrel carb does not help performance

[Scott 02]

Ok, Thanks. It makes better sence now.

4 barrel carb

Have fun swaping it, It really is a B****

No, thats why they make intake manifolds.

[450HPviper]

Scott, you have never seen a 351C in your whole life and have no clue about what you are saying. Stick to the chevys if you think they are so great.

[Scott 02]

I will and I shall. They are the best!

Getting better performance out of your 351 Clevo aint all that hard.

4 barrel manifolds are common here in Australia and there are even after market ones offered.

the best mods are to replace your 2 barrel manifold for a 4 barrel, fit a 600 Vac secondary Holley, a mild cam, and extractors. If you have 4v open chamber heads replace them with the closed chamber 302 Cleveland 2V heads (common in Australia).

If your stuck get onto the Ford Forums and poke your way into the Australian section.

make sure you have the 351c and not the 351m first. also in that years you could have the 351w. if you have the 351m, you have a couple of options;
1: yank and install a 400 crank and pistons, the rods are the same, and use the 302c aussie heads and build a good 400.
2: yank it and ddrop in a 460
3: add some mods like the 4bbl intake and a cam and aussie heads and live with a decent but not really powerfull motor that does few things well.

you can tell which option i would choose.

There is a good book on Ford V8's. Ford Performance by Pat Ganahl published by S-A Design Publishing Co in California.

ISBN 0-931472-05-9

This book covers the four main Ford V8's and has been a handy reference for me over the years.

Clevelands when set up properly are more reliable than the equivalent chevy, especially the "2 stroke" oil suckin Gen III's.

Enjoy
