chad:Stock Factory 4-1/4" EOBE 9430 KE header

[xctasy]

For chad.

And for everyone who has found all the aftermarket body and air condtioning snarl ups with Hooker and Speed daddy dual out tubing headers,

check the cast iron header Ford made from 1980 to late 1983.

Its

1. space efficient,
2. compatible with Air Con,
3. and a lot better than stock factory header.
4. For the years it was around, it made an extra 9 net flywheel hp over the earlier 2" outlet exhaust, and
5. has provisions for Secondary AIR and EGR.

Information from production 6 cylinder racers is that a dvided twin outlet iron header usally makes more torque without a power loss of the pipes at the manifold flange are kept separate rather than combined as forced by the factory foot ball catalysting


A quick note.


The 4-1-4" out let exhaust is found on three engines from 1980 to 1983.

The iron header is sized to fit this catalyst, which was used with the later 1969 onwards Center Purcussion (forward mounted, F150 Big Six type) engine mounts. If equiped with the standard cat, it won't fit most X chassis 200/ 3.3 liter Fords from 1960 to 1979, but that's because of the catalysts size in conjunction with the earlier 200 Ford engine mounts. Without the catalyst, there is ample space for two up to 2" header pipes to replace the primary "football" cat shown here

200/3.3 B code 1980 to 1982 Fox platform

(click picture care of powerband's link )

200/3.3 X code 1983 Fox platfrom


and the one year only 250/4.1 C code 1980 Monarch/Granada


It used a primary light off cataylst which you can still buy from Catco under #66991

Without the cat attached, it will fit any engine bay.

You find the exhast on ebay all the time

Casting no EOBE 9430 KE


Replacement cat is around.

OnN Fox bodies, the primary light off catalyst is normally stamped E1 BE 211 with a letter suffix A, or E for secondary AIR.
On the 1980 X cars, E0 DZ 5E212 A or E (for secondary AIR)

Replacement is now Catco #66991

Part numbers are under the American Granada, Monarch and Versailles

The big foot ball converter B and X code exhaust found on the 3.3 Foxes from the 1981 model year had a large single outlet



which can be divided up two or four ways. The single approx 4.25" hole can then run two exhaust pipes, sort of like this Opel 1900 twin carb header



one pipe can then go under or through the sump.

That allows you to run a 5.0 style full dual exhaust system, even with quad pipes if you wanna look like Daniel Boone packing a Pen Long riffle.


The stock 4.25 " exhaust football converter B and X code 3.3



It can be divided up into two pipes, and then one led under the engine to the left, and the other to the right, so you can run a V8 style exhaust.

Two images of a low mount block small six with a sump with a cross over pipe hole in it. This doesn't have the large 4-1/4" header, but you get the idea...

Thank you.

I followed a link there and saw a fella standing in an engine bay playin w/a (n. american) football or rugby ball, sure wasn't a soccer ball cuz it aint round (my family calls em handegg cuz U use yer hand, mostly 'n they're shaped like an egg, but we're different, very different).

1st thing I noticed was an ex. manifold that (as told 2 us by 4 eyed pride dot com) fits all our "sm 6s". 2nd thing (4th pic) was a rear sump oil pan I need to put the 250 in a bronk. BUT it was on a 3.3. Wonder if there's one on a '80 USA Granada 250?

Anyway, last I saw garage fabed pans with passages for ex. pipes. Pretty crazy!

I'm wonderin is that football exhaust split (pre collector or football) like our 300 EFI motors? Ie where U state "...can B divided up…"

Or does that just mean make a collector at the "football" & run yer secondary lines at that same point? May B I better look at all yer links (if I do this post will B lost, back later).

EDIT:
Back now, yeah w/my short money - make a collector right at the football that splits w/ 2 very short pipes 1 inside, 1 outside the frame?might be the ticket. Gotta go look...

Two things. 1. EXHAUST AND 2. SUMP.

Exhaust first. Just requires two down pipes into the big 4-1/4" hole.


The Holden in Australia just used an adaptor to cleat the two down pipes.
Like this. The four existing bolts will do the same job. You 'raiders of the lost part" the catalyst o ring, and make a plate out of quarter inch plate and have to two down pipes joined via the common down pipe "o" rings.

Like the Walker Down pipe for 4.9's and dual headers only...you don't need dual headers.

From 1965 to 1973, all the high performance 145 to 190 hp GM Holdens in 179, 186 and 202 form head dual out headers. It returned again in 1980 for five years again in the 102 to 120 hp 2-bbl engines, and then in 1985 in the 142 hp 202 Electronic Injection header

Here is the 1981 3.3/202 Holden engine's down pipe

Here's the earlier 3.1 liter/ 186 dual out down pipe

2.SUMPS.

Grab any Fox 3.3 sump and pickup, and copy and paste, um, cut and shut it into the existing Ford 250 sump.

There are no rear oil pan sumps for the US 250. You have to make one MustangSix or Mike1157 style

There was a reason the rivited on external dip stick early bronco V8 sump was made...it was a first of its kind. For sixes, you can easily redo a sump.

All the US 250 frames it was in,
the X shell from 68 to 80,
the separate chassis 972 and 73 Torino used 100 and 98 hp L code 250 for two years
...but sadly still used the X shell front pickup sump.


In Australia, for the Aussie F100, Cortina, Transit Van, plenty of rear sumps.

For USA or Canadian made, its only

66-77 early Broncos,
75-82 4x4 F trucks, Broncos and F150's with the 351m/400's used the rear sump oilpan.
75-91 E vanS
79-93 Fox
82-04 S-shell (what the new Fox frame officially became in 1982 to 2005)
80-10 Panther frames

that have rear sumps.


None of them had 250 engines.

thnx,
i'll braze the 'ring' from 1 tother, 'roll' some 'sheet goods' or 'cut the corner'
like the new comer did - that bridge i'll B crossed when I get there.
How bout this 'foot ball'? I guess I'll hafta make a collector and Y, or
may B a 6 to one...

Duplicate the stock down pipe twice, side by side this way.

A hacked up stock cat downpipe would look like this

Then you have the option of the stock 4.9 truck/Walker/dual out Hooker/Speeddady/ XU1 style,

OR the classic V8 dual outlet via underslinging one of the pipe under, through, or behind the sump.

The 4.9 Pontiac Turbo used this set out.

The 2.3 Mustang turbo ran the exhaust behind the sump.

All great ideas!
I like stock as much as possible. May B a home made collector in that "stock cat area" tho. There might need to be a smoother transition from the "metal o ring" to the two 2 1/8 inch outlet pipes in the pic. I believe a 1/4 inch plate, funnel-like structure or sectioned cast iron plumbing hub might be fabed for this purpose. Having no automotive theory knowledge I believe I'd Iike to see a 6-1 for my purpose. Also with out theory - an idea that a 2 1/2 inch outlet at the "cat/collector" would be desribable. Not sure if this neck-down would hinder scavenging and flow needs for the low rev high tg results I seek. I'll only pipe as far as the front of the pass. rear wheel with that 2.5 inch (& may B thru the sheet metal there as it's a LUEBer - will stay so). Not sure if the systems gets a resonator and muffler at this time either. As a parts man I have a muffler some 1 returned but the vendor did not want back. It's small enuff to tuck up well out of the way of rocks and branches driven over. I'll use that and have a shop make up some 2.5 pipes. I'd like to use some rubber in the hangers but may go solid all the way. I have been thinking I'll need heat shields as everything will be close to the floor boards. Any ideas about what material, how to hang it?
