1952 fresh powder coated twin-h exhaust manifold for trade for correct manifold

This might be a great deal for someone!

A guy I know was trying to replace a cracked exhaust manifold on his 1952 Hornet. He bought a replacement manifold that he thought was the same.



Only after sending it out to be powder coated and spending $200 doing so did he realize that he had the wrong manifold. He thought basically all twin h were the same. As I'm sure you all know this is not true. Thats like saying all women are the same.. SO NOT TRUE!!!



The difference mainly on this one is the bottom of the manifold where it bolts to the collecter I'd guess you call it. Everything else look the same. Originally when he started the project he had 968S carbs which he's keeping but needs the other manifold setup. I do not have any of these.



He is willing to trade the one he just had powder coated which is in perfect condition for the correct one he needs as long as its in decent shape. He'll then powdercoat that one instead.



Now I'm not real familiar with the different applications but from what I understand there are maybe 3 different applications for 52 based on whether its a automatic - 3 speed with OD - or export - whatever that is.



It looks like the only difference is the bolt pattern on the bottom of the manifold and 1 extra bolt hole and a slightly different ported opening.



Here are pictures of both manifolds. The correct broken one that he needs to replace and the incorrect one he already powdercoated. To show the difference.



I also have some numbers off of the manifolds etc but the numbers on the original are about impossible to read. If anyone has one of these they could sell me that would be great or like I said at this point this guy will trade his new one for the correct one.



Unfortunately he didn't say anything to me before buying the one he did or sending it out to be powdercoated but now out of frustration wants me to finish his car up for him.



I owe him a favor so I told him I'd try me best to locate one for him.

If anyone has one please let me know what you want for it or I can trade you....or if you need any other stepdown parts I may have them and be willing to trade those as well.



Please let me know asap....its going to be 86 here for the 1'st time in forever this weekend and we would love to go for a ride in the old 52 this weekend.. I'm sure with everyone on here we can come up with something.



Again 52 Hornet Twin-H 308 with 3 speed OD exhaust manifold if you need any other pictures or numbers please let me know.



Thanks guys!!

    Mike - I think the one you show as incorrect is for the AMC 308, 1955 thru 1957. The one you show as correct is for years 1948 thru 1954 all inclusive (232, 262 & 308). As far as I know, there were no differences in the exhaust manifold for each of the various transmissions.

    I think jerry has it backwards, but if he is correct, I'll swap one with him.

    the only difference in 52 would be single vs twin H but changing the studs and adding a hole for the choke takes car of it. as they are the same casting

    As far as I know, Hudson (AMC) never made a twin exhaust outlet available for the 1955 thru 1957 308 which had 4 bolt patern. The original Hudson 232, 262 & 308 exhaust manifold uses the 3 bolt patern for the exhaust outlet, and the twin exhaust outlet I'm looking at right now has the three bolt patern.

    ok Jerry you're upside down not backwards:D. thats the mating surface to the intake he's showing, not the exhaust outlet.

    Is the intake possibly from a 55-56? It looks like the one pictured has vacuum ports, which I thought were AMC. Does intake have an integrated balance tube?

    I may be upsider down Nick, but the bolt pattern goes all the way thru, and attaches the outlet to the bottom of the exhaust manifold. It is definately a twin H for the 55-56 & 57 308

    I find this an exhausting subject, however the thought of powder coating engine parts has crossed my mind. Has anyone had success using powder coat on intake manifolds, cylinder heads , lifter covers, oil fill tubes, throttle linkage and other stuff I cant think of? Will it discolor with the heat?

    Ok, I went out and looked, I am running the hash manifolds on my 54. There are only three studs to attach to the intake and they do not go all the way through to the outlet. the "incorrect" is definitely not a 55-56 exhaust but that is definitely a 55-56 intake in the first picture.

    Well Fellas there is alot of banter going on ... but here is the real answer: The exhaust manifold the Hudson owner needs in from a Hudson twin H that has the integrated vacume tube... most would immedinately say ... the 55-56 twin H manifold. I would have said the same thing myself. BUT I did some research. The parts books for 52-56 all the individual years and the master parts illustrated books show a 4 bolt exhaust manifold illustration. But for the 55 and up with an integrated tube intake this is correct... dah... look at the pictures. The bottom of the 55-56 manifold will only mate to the three bold varient. The alternative is headers.
