Open Box Special - 351 Cleveland intake manifold with casting numbers. This manifold has been opened, checked for fitment and returned. Our returns for this Cleveland manifold are almost always predicated on customers not checking/knowing what cylinder heads they have. Remember this manifold is for the 4V 351 Cleveland application! We are selling this at a discounted rate as there are blemishes on the intake surface, again, due to customers checking fitment. Other than the intake surface blemishes, this manifold holds the presence of a new Blue Thunder intake manifold. Why sell it at a discounted rate then? It wouldn’t be honest otherwise!


This listing is for the Blue Thunder aluminum 351 Cleveland four barrel, dual plane intake manifold with casting numbers!


I first started purchasing this manifold 35 years ago. Since then there has been a few tweaks to the casting that have upped the performance. I have personally seen this manifold pickup 36 hp without giving up low end torque; just by switching the manifold!


I have been told this manifold is worth as much as 74 hp when you port match your cylinder heads, and fine tune your engine. I've personally seen 52 hp after port match and fine tune.


Let the pictures tell the story for you. This beautiful casting that has been shot peened with stainless steel to keep a natural bright aluminum finish that won't change colors and rust. More things that set this manifold apart from others: AUTHENTICITY! It is not difficult to make this manifold look like an original Ford factory manifold, unlike other manifolds this has the heat riser on bottom as well as other important original features seen in photos! Why is the casting number so important? We worked close with the manufacture to get the casting number on this manifold due to the numerous issues with smog regulations within the state of California (and other highly restricted emission states) which will now be resolved.


The manifold has been pressure tested in the, heat riser, and runners to 60 psi. Blue Thunder manifolds are highly detailed, what you see in the picture is the same quality you will receive. We don't & won't take pictures of items that are not representative of the piece you will receive.


I have used other aftermarket manifolds, and I can tell you without a doubt; this manifold is the best piece available. If you're tired of other manifolds that have weird names cast on them, no heat riser, rough casting, misaligned ports and leaks; this is the manifold for you.

Question:

*PLEASE NOTE THAT THIS QUESTION WAS ORIGINALLY PERTAINING TO A BIGGER FE MANIFOLD CASTING, BUT STILL APPLIES*

I purchased an E********k manifold last month because the Blue Thunder manifold was not available, and there are holes and what appears to be gas in the manifold; what should I do?


Answer:

I’m really glad you asked this question Derick, and if you don’t mind I am going to use your question on our eBay page. If you have already purchased the manifold and you’re sure it will work for your application I say use it! Just because the casting isn’t perfect doesn’t mean it won’t work. You will find the bigger a casting gets the more likely it is to have some kind of flaws, even in the Blue Thunder piece. The question is do the flaws effect the functionality of the manifold? You should still inspect your casting and if there’s issues with gas/porosity in pertinent areas such as water jacket and/or holes going from pushrod to port like we commonly find with other manufacturers. If so, we suggest contacting the manufacturer of the manifold to see how you would like to proceed. Remember to have reasonable expectation especially with a large casting like the FE, and just because they don’t measure up to the Blue Thunder casting doesn’t mean they’re crap. We use other manifolds in our shop as well but our-go-to-manifold is always the Blue Thunder.



Question:

I bought a similar item from someone else on eBay and they never arrived, what do I do?


Answer:

You need to contact the person you purchased them from first. If you cannot find resolve take the next step and file a clam through eBay. Once your problem has been resolved feel free to place your order with us.



Question:

Do you take deposits?


Answer:


We’d love to take deposits as much as the next store, but there are people who will promise their customers anything to get their money. The process of taking deposits in this industry has been burned many times over. The best way to keep a clean reputation such as we have is to do business on the up-and-up, for us that means selling product when it’s available; and fronting all the capitol for purchase (not using customers money for capital), so we do not take deposits unless it is something very unique we are doing for our customer.



Question:

Do you offer these manifolds painted?


Answer:

Yes, on occasion we set-up to paint these manifolds; but we will need the specific color code you are using. For the best match possible we will need you to provide the the exact brand paint and color code on can you’ve used in the rest of your engine. We charge a flat $50.00 plus cost of paint (usually $10.00 depending on paint). Please keep in mind this process takes an additional 3-5 days for proper paint curing (depending on paint). We stock and have most paints available, in the event we do not have your specific color available you will need to tack-on a few additional days.



Question:

This is a lot of money for a manifold, what makes it so special?


Answer:

Well, we added a little extra narrative in our description this year to give the customers a better idea of what they are paying for; because you are not the first person to ask this question, so we’ll answer it in two parts.


Part1) The best way to sum this up is that you’re not purchasing a commodity item. Every manifold is handled dozens of times by numerous different employees, this ensures that nothing gets missed before going out the door. After having long talks with the manufacture they describe their merchandise as table dressings/jewelry. If you bought your wife a beautiful diamond ring and within one month the diamonds start coming out you will be an unhappy customer. Blue Thunder does not have unhappy customers because merchandise is falling apart, they have unhappy customers because long production times! The way Blue Thunder explains it to me, they wouldn’t have it any other way “the faster manufacturing go’s the more chance things get missed, and we’re not going to miss anything”!


Part2) Blue Thunder only uses the finest materials and equipment available for their manufacturing. It starts when the manifold is cast from Aircraft certified foundries and finishes with their method of cleaning the casting before it’s packaged. You will not find embedded material on their product that will find its way into your engine, like so many others! Every time I speak with the people at Blue Thunder it’s very clear that every step has been meticulously thought through. This is why they have one of the finest names in the Ford industry!
