Exhaust Manifold Question
Hey guys Ive got a 78 250 4x4 with a 460 and c6. My problem is that my exhaust manifolds are full of cracks. My ford buddy guru told me that the motor is out of a 73 van. I was thinking about getting headers but am leaning more towards just throwing new manifolds on there. The issue i keep running into is that 75-79 manifolds are all over the place and really easy to find but i cant find 72-74 manifolds anywhere. Do you guys think that 75-79 exhuast manifolds would fit on my 73 motor? If so it would save me a buttload of time. If not any idea what the difference is? Thx for the help

I think the only difference would be the 72 has a different frame, so 79 manifolds may not clear a 72 frame. I would think the heads would be the same as far as bolt pattern. Just get some 78 / 79 manifolds , you may have to change the way your pipes are hooked up if they are connected to an older manifold.

My ford buddy guru told me that the motor is out of a 73 van.
There is no such thing, so...you won't find any exhaust manifolds.

I wonder why...

This Ford parts guru sez: The first year for the 460 in an Econoline was 1975.
460: 1975/86 Econoline / 1975/79 F100/350 / 1983/86 F250/350's use the same exhaust manifolds // 1973/74 F100/350 460's use different manifolds.
The 460 was not available in F100/150's after 1979, it was not available in any F Series truck in 1980/82.
But, the 460 engine may be from a 1968/78 passenger car, which uses different exhaust manifolds and so...will have different locations on the manifolds for the exhaust inlet pipes.
Look on the manifolds for ID numbers, post what they are.

No Ford Dealer or obsolete parts vendor has any of D5TZ9430C / GREEN SALES CO. in Cincinnati OH has SIX of E5HZ9430D = 800-543-4959.
There's a bunch of F2TZ9430C around, but the last MSRP was...$948.78 !!

Your Ford buddy guru is mistaken. The only V8 available in a 1973 van (1969/74 Econoline) was the 302.

That is incredibly helpful. He said he thought it was a van motor because the dipstick was one of those really long windy pain in the butt tall ones that they had on the vans because of the decreased engine compartment size. I found the stamp on the side of the block right underneath the row of spark plugs that tells the year, since the first two letter/numbers are "D3" Where on the exhaust manifolds would their serial number be and what would said serial nuber look like?

I looked on my manifolds and this is what the drivers side had on it 3J1O(on what looked like a metal tag that had a screw holding it on) then a couple inches away from that up in the corner it had an 8, the only thing i could find on the passenger side was a 9 or 6 depending on how you look at it. Dont know if that gives you enough information but if it doesnt i can go check again.

Where on the exhaust manifolds would their ID engineering numbers be and what would said numbers look like?

D3 doesn't mean diddly-squat...it's not the block casting number. The following are for 1971 thru at least 1986:
Look on the engine block near the starter for the casting number.
If: D1VE-6015-AB, AB1, AB2: 1973/78 Passenger Car / 1973/78 & some 1979 F100/350's / 1975/78 & some 1979 Econolines.
If: D9TE-6015-AB: Some 1979 F100/350's & Econolines / 1980 and later Econolines / 1983 and later F250/350's.
The D1VE engine does not have a weighted crankshaft spacer. The D9TE engine does.
With a mile long engine oil dipstick, the 460 would most likely be a from a 1975/91 Econoline.

With the DIVE casting number, the 1982/91 Econoline 460 dipstick was used as a replacement.
What you have, IMO...is a 460 from a 1975/78 or early 1979 Econoline. Since Ford didn't offer the 460 with 4WD until 1983, it's obvious the engine was swapped.

D1VE = 1971/73 Passenger Car 429 / 1973/78 Passenger Car 460 / 1973/78 and some 1979 460 F100/350's & 1975/78 and some 1979 Econoline 460's.

so I was ready to quote the above info.The D1VE engine is essentially the same 1971/78, it was also used in some 1979 F100/350's & Econolines. No cars had 460's after 1978.
In midyear 1979, Ford changed the 460 engine, the block casting number is D9TE-6015-AB
This engine uses a weighted spacer, the D1VE does not. The harmonic balancer and the flexplate used with the D9TE engine are different than was used with the D1VE engine.
The 460 was not available with a M/T until 1983.

Hey Bill sorry havent been able to get back to you for a couple days, swamped at work. I just want to say how much I appricate your help.
And I have a few more questions
. So now that i have a list of manifolds that will fit I should be able to find those. But assuming my truck has a 75-79 econoline 460 there are some other modifications i want to make to my engine like new distributor ect..So is there any way to determine exactally what year it is or am i safe buying any parts for any 75 to 79 econoline 460?
Also where in your opinion is a good place online to pick up good OEM new manifolds for my rig?
