Is there anywhere that sells new exhaust manifolds for a 1978 F150 with a 302?

.

 

LMC has manifolds for the 351M/400 for $129.95 each, however I don't know that they would work on a 302. Since the 302 and the 351 Windsor I believe are interchangable. Someone correct me if I'm wrong here.

 

.

Yeah, I'm pretty sure the 351M/400 manifolds won't work.

I have some 351M/400 manifolds on the hunk of trash I pulled out, but now I need some 302 manifolds for the engine I put in.


The hunk of trash...

 

I am sure Bill can get you OEM part numbers but you might try JBG they list them for all the other engines availible in these trucks except the 302 in the online catalog but I would call them and see if they list them for your application. Just one idea anyway, you might also check with your local ford dealer you never know.

 

if your already replacing them, i would put headers on.

 

Is the truck 2wd? If so, I would switch to headers, otherwise if 4wd use the manifold.

 

.

eh, I thought about headers, but I think they'll be more of an aggravation than they're worth. I'd use them if I can't find some cheap stock manifolds though.

I need oxygen sensor bungs welded in each side, and it would be a lot easier with manifolds because the exhaust guy can just put them in the pipes when he does the exhaust, and no wire harness extensions would be needed.

If I use headers though, I'd have to have the oxygen sensor bungs welded into the collectors, then I would need some extension harnesses for the sensors. It's possible that I would have to install the headers, then remove them to have the bungs welded, then put them back on... just depending on where the bungs need to go.

I'll be going to a junk yard soon, I may check there for something used... but used stuff is sometimes a headache too.

Both manifolds are obsolete...but there are a few new originals (NOS) still available.

That's it. No other dealer or obsolete parts vendor has any of these manifolds NOS (New, Old Stock).

Since the Ford and L/M dealers are STUCK with them, the price should be somewhat reasonable, as they can no longer return them to Ford.

Casey_78: No 1969/79 F100's or 1975/79 F150's w/302's came with 4WD...all are 2WD.

Excellent information, Bill! I don't know how you do it, but you truly are amazing

I'll give them a call later today, and hopefully I can get both from Green Sales Co. since they have at least one of each, but I'll check prices at the others for the left manifold to see who has the best price.

I think that manifolds should flow well enough for my stock 5.0 HO that I'm swapping in?

.

 

Green Sales will be much higher in price than those two dealers will want for them, that I can assure you!

Usually when dealers are STUCK with anything that's obsolete, the selling price will (usually) be the dealers original COST price + 10%.

With Green, as with most of these obsolete parts vendors, the selling price will prolly be the original LIST price + who knows?

Will these manifolds flow the way you want them too? That I cannot say.

How do I do this? Piece of cake...as I have the parts catalogs, and two places online to search for parts...obsolete or not.

One is the in-house Ford dealer (only) parts locator system, the other is partsvoice.com, that anyone can use.

 

I realize the post is 5 years old but I need a pair of the manifolds for a '79 F100 302. If you're still around the forum can you check availability? Thanks.
