Exhaust Manifold Question 1968 200 cyl

[Anonymous]

First post here, excellent forum...Greetings Everyone
I am in need of a exhaust manifold for my 68.. I SEE PLENTY on ebay and elsewhere but only see up to year 1967.. 68 is much more expensive if I even see them... what are the differences? can I use the 67? my car is currently all stock and no smog or emissions stuff is on it... Input appreciated ...

yes u could use an exhuast manifold of any 200 but there are some differences as they have changed little by little but u can use any exhaust manifold off a 200 just some of the later years ones were made differently and are stronger







and by the way if u are looking for an exhuast manifold i have the one off my 69 motor i could sell u the only problem it that there is still about a foot of exhaust tube still connected because i couldnt unbol it from the manifold id be very willing to part with it for very little money

The exhaust manifold for the 68 has a headpipe with a 2" diameter, vs the 1 3/4" for the 67 & below.
The 68 manifold is a good hop up for the earlier cars if you don't want to go the header route. William

Interesting - my 1970 Maverick with a 170 was 1-3/4", while my 1970 Mav with a 200 was 2"

I dont know who's closer but I also have a manifold sitting in my garage if you need it.

Well if it is from a 68 and in decent shape and a 2" I would be interested, I looking to replace because 1 of the bolt holes is broke off, and I looking to get a new exhaust and dont need any leaks...how much? paypal personal check money order etc...Thx...also thx to all that have replied....

I went ahead and got a new exhaust manifold from NPD (National Parts Depot). It had a casting saying it was a 78 manifold. And there was also a HUGE threaded hole in there. As a quick fix, I screwed an old sparkplug (coincidentally the threading and size matched) until I went to the parts store to find something more permanent. The pipe diameter was 2" and fit a stock 68 system. And yes, it was quite a pricey item. Almost should have just went and bought headers instead, but I needed something then and there for my only mode of transportation back then.
And just FYI- to me it was almost worth the cost of having a newer manifold than dealing with that or another old one.

Howdy All:

What I know- early manifolds (196- - '62) were very prone to cracking, had a flat gasket to pipe surface and a 1.75" outlet. Later manifolds are heavier cast and gusseted in weak areas. All later manifolds use a donut gasket and a "firewall" sealing system to the head pipe.

'63- '64 are only slightly heavier than earlier castings. '65 -'66 are slightly heavier. '67 - '68 Pre smog pump castings are heaviest, and cleanest- as far as extra casting, taps and bungs. '69 - '78 saw many iterations of EPA fixes. They are more crack resistant then earlier castings, but have unusual shapes due to smog taps, bulges and bungs and some '79 and later castings got the direct mount, quick light, catylitc converter attachment,

Linc- would you check the casting number on the small outlet 170 exhaust manifold for me. If it is the original it is very unusual. (NOt unusual with FoMoCo) Thanks.

Adios, David

Need to find it first - - engine is in a shed on an abandoned farm...I could have SWORN it still had the exhaust manifold on it, but it is GONE....I don't remember ever taking it off, no reason to.

Block casting is C8 and casting on intake log is D0DE
