1986F150Six Posted September 28, 2017 Share Posted September 28, 2017 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! Link to comment Share on other sites More sharing options...

Gary Lewis Posted September 28, 2017 Share Posted September 28, 2017 Yep, that's the one! Thanks for helping, Jonathan! So, what's the plan, Stan? Link to comment Share on other sites More sharing options...
PetesPonies Posted September 28, 2017 Share Posted September 28, 2017 So, what's the plan, Stan? Like this one? Very similar. Link to comment Share on other sites More sharing options...
Gary Lewis Posted September 28, 2017 Share Posted September 28, 2017 Like this one? Very similar. 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. Link to comment Share on other sites More sharing options...

Ford F834 Posted September 28, 2017 Share Posted September 28, 2017 Like this one? Very similar. 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. Link to comment Share on other sites More sharing options...

So, with the one Jonathan posted and the one Pete found, I'm thoroughly confused. http://bullnose-enthusiasts.12971.n8.nabble.com/file/n2088/300_Exhaust_-_Stevens_Parts.jpg 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: https://fordsix.com//viewtopic.php?f=2&t=56939 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. Link to comment Share on other sites More sharing options...
