I'm reassembling the rebuilt flathead V8 for my 51 F3 and having trouble finding exhaust manifolds. I've found a guy that says he can build the Y-pipe and everything aft of that to OEM configuration, but I haven't solved the manifold issue yet. Don't really want to go headers and custom exhaust as we're trying to keep this project as close to OEM as possible.

Any advice or suggestions on where to find these exhaust parts will be appreciated.

 

I recently rebilt my 239 Flathead V8 (52 F-6) and was able to use Ford part number 21A-9430/1 headers just fine (these are older Ford headers from the 30's and 40's I think). Many early Ford part dealers have these in serviceable condition for earlier V8s. I was really hoping to obtain the proper 7RT-9430/1 headers, but they are pretty rare it seems. I settled on the 21As as they are essentially identical and fit just fine. All the new production headers are seemingly destined for fitting headaches and are geard towards the modder/hot-rod community instead of the purist. In my searches, I have been warned that the passenger model 8BA-9430/1 headers will not fit appropriately around everything in the engine compartment. A quick search has revealed that Little Dear Born may currently be a potential Source for the 7RT-9430/1 and other exhaust parts:

Good lead. They were able to help with new and used parts. Problem solved. Thanks for the tip.

 

i have a set of factory 8ba manifolds is great shape

 

That's awfully nice of you needhelp49 if there is someone looking for a set of passenger vehicle exhaust headers:

 

well, i have a set of original manifolds off an 8rt. one is a 7rt-9430, the other is a 21a-9431. to my knowledge, they are original to engine, and are as clean as when new. no pitting, or damage of any kind. does it make sense that ford would mix the two? or was one maybe swapped out very early in engines life? if only engines could talk.

 

not sure what the numbers should be? but mine are original to the truck i know the whole history of the truck and these came with it. I've been holding on to them but i now want all extra truck parts gone.
