[mikelspower]

Can anyone help me with a 351 Cleveland ideas?

....? You gotta give us a little more to run with.

How much horsepower are you wanting to make?
Do you plan on building a stroker? If so, how big?
Do you plan on a power adder?
What is the primary use of the vehicle?
Rear gear?
Trans type? If auto, what stall?
What type of camshaft are you planning on (hyd flat, solid roller, etc...)?
Carburetor or EFI?

1. I would love to stroke it, but I don't how big.
2. I would love to supercharge.
3. Weekends, no racing.
4. I have a C6, I don't which size to go with.
5. I have the cam, will have to look for the spec. on it.
6. Carb

How much boost do you plan on using?
Which blower kit are you looking at using?
How much horsepower are you looking/wanting to make?
Do you know what the rear gear is going to be?

Please verify the camshaft specs at your earliest convenience.

I was looking at paxton, because I have used them in the past. I thought 5 or 6 psi. I would like to make around 450 to 500 hp, if possible. I have a 398 gear for the rear.

You don't need a blower to make 450-500hp especially with a stroker. A relatively mild 408 with newer aluminum heads will get the job done without breaking a sweat.

A little bit to get you started. Clevos can make good power even with the cast iron heads, but they are very dependent on getting the right cam. The Al CHI and AFD heads are very good and so are the Al c302b Ford Motorsports heads and all will get you benefits over the iron heads. 500 hp is easy with a 408 stroker and iron heads and 600 is straightforward with the aluminum heads. There are some new Al heads from Trick Flow that you can buy from Summit. They are very new so there isn't any info yet on how well they work, but they look pretty nice.

You need to be careful with the stock blocks to make sure and do a sonic check before even boring them .030. The stock cranks are very stout even though they are not forged. There are some minor oiling mods that help longevity.

I have a 351 cleveland, are you talking about 351 w, 302?

[Declawed69]

c302b ---> these are aluminum cleveland heads


although I'm not sure where the tfs heads came from I can only find windsor heads

[cudaman]

In terms of all-around drivability with the best powerband for the street, is it true that the best combination of factory parts for that motor was the 2V heads with the 4V intake, as far as stock parts go? I always heard that, but never had any personal experience with it. Seems like the intake had to be slightly modified, but I can't remember.

I was talking about 351C not 351W. I've run both 351C blocks and 9.2 deck ford svo race blocks with cleveland heads. Depending on power and rpm level the 351C can work just fine. They are a good stout block - you just need to be careful with overbores because they are thinwall castings. But you can also use windsor blocks (the CHI and AFD heads have water passage plugs that work for C or W blocks). The new Trick Flow heads I was referring to are clevelands - they are in the latest summit catalog. http://www.trickflow.com/pressreleas...PortCleveland/I can direct you to some places to learn more about C motors and heads if you are interested.

Thanks you, that would be great! My 351 is already 30 over, can you go more?

[funcars]

Sent you a pm with more details. .030 for most 351C blocks is as much as you should go. Don't run a 4V intake with 2v heads or the other way around. There are new Al manifolds available for either option now that work well.

What do you think about...AFD Small Block Ford V8
Cleveland Cylinder Heads?

[funcars]

They are not as popular as the CHI heads (that's what I have), but I know some people have had good luck with them. I would not buy a set off of e-bay though. It would be better to contact AFD directly and talk to them about what you want. They have multiple options for chamber volume and port size/configuration. You can do the same with CHI as well. What are you trying to do with your motor? How much power are looking for? How much can you afford to spend?

[mikelspower]

I would love 450 - 500 hp.

[funcars]

450-500 is pretty easy with stock stroke and good heads and no supercharger needed. I'd go with smaller aluminum instead of big 4V iron heads. Smaller Al heads will have more torque and don't need as much initial timing. Look at the CHI and AFD websites and see what you think. C302b's would be OK too, but the exhaust ports are higher and it is tough to fit headers in some cars (especially early mustangs). All the above can use Cleveland or BBF rockers and valve train pieces. If it was me I would buy the smaller port CHI heads and their mating intake and run them out of the box with a good cam and about 10.5/1 compression flat top forged pistons. You'll do well above 450 hp and can run on pump gas. Let me know what you decide on.

[mikelspower]

Thanks, that sounds good!
