Looking for a part...

Ford 300 heavy duty exhaust manifold, used in medium duty trucks.

It looks like the following photo of an aftermarket one: http://i.ebayimg.com/images/g/I28AAOSw-EBZto4f/s-l1600.jpg

Thank you!

From the 1973/79 Heavy Truck catalog, it looks like the part # would be D9TZ 9430-A, which is what the box would say according to Bill and Chris, but the part would be marked D7TE 9430-EC.  Rear Counter says there are 4 of them in captivity, although I didn't request a price.




But Stevens Parts says there is a D7TE 9430-FC casting number.  So, with the one Jonathan posted and the one Pete found, I'm thoroughly confused.

Sadly that is the regular straight six manifold. You can tell right away by the 45* outlet angle, two bolt head pipe flange, and heat "flapper". The HD manifold points basically straight down, and has a three bolt head pipe flange. The exit diameter is much larger which is the whole point of upgrading.

There are versions with and without the threaded pipe port in the rear for EGR tube? Also there was some discussion about a version with four bolts attaching the intake log to the exhaust log. This one won't work for us unless you get the matching 4 bolt intake. It would be good to get to the bottom of this to know for sure which ones will work with our intake and which ones won't.

Here is a good reference thread on the HD manifold:

Edit: if anyone is wondering why David does not just buy a new one from Stevens, evidently these Chinese cast reproductions have a problem with cracking... and they are not exactly inexpensive to turn around and have that happen. That is why it is worth the effort to hunt down an OEM part.

The flapper I could see, didn't notice the three bolt flange. That's why I said similar. I just use the EFI manifolds when trying to do better than the factory log. I have installed two sets of them.

To continue the discussion, it looks like there were two intakes.  Note that on the previously-posted clip it takes 2 studs to join the intake to the exhaust.  How does that square with what is being said about there being 3 studs?

Gary, every 300 I have worked on had 3 bolts holding the intake and exhaust together. The HD 300 in the 1970 F-600 dump truck we had at scout camp had the 3 bolt exhaust pipe flange. I am pretty sure it had 3 bolts, and I believe two were one direction and one the other.

Just to clarify: the number of bolts that join the intake log to the exhaust log is one issue. 3 bolts being what you need if you want to join it to a regular light duty intake manifold. There are HD manifolds out there that fasten with 4 bolts and won't do you much good unless you have a matching 4 bolt intake manifold:





This is completely different than the number of bolts that fasten the head pipe to the exhaust manifold. The HD uses a three bolt flange, the regular light duty one has the ordinary two stud configuration:

Yessir, Gary, that is exactly correct, and you don't need to listen to me or Bill when it says just that in the catalog....

The Part Number is a xxxZ prefix and is listed in the catalog.

The casting/ID number is depicted in the catalog prefaced with a hash mark/pound sign in the RH column.
