I am in the process of swapping out the 318 Poly for a 440 Crate motor in my 65 Fury III. I have a set of Headman Headers for a "B" body but there is no way these are going to fit in the 65. I have a stock set of exhaust manifolds for a truck application but there is now way the driver side - center dump will work in ght 65 :spank: no clearance at the steering box. I searched the Web for pics and info for a driver side exhaust mainfold for a 65 Fury III with a facotry 383 and could not find anything definitive. I found a driver side - passenger car big block manifold with the rear - angled dump on line. It looks like it will fit fine but without it in my hands to fit up, I am not 100% sure. Before I order it, I was wondering if anyone out there has done this swap, has any pics or any info to help me out. Thanks in advance for your replies!

Don't understand your problem the 65-68 were available with the low deck 383-B and the raised deck 426-RB, Wedge. Anything that fits them will fit a 440-RB. Additionally, the years of 60 through 75 offered many same/similar combinations of low and high deck big blocks much of the exterior stuff like headers, exhaust manifolds, intakes, and engine mounts interchange across these years. The heads between the low and high deck blocks are pretty much the same so bolting manifolds/headers should not be a problem that can't be worked. You have to remember between stuff for low and high deck blocks the intake has to be common with the chosen block as the heads get further apart on the RB than the B block. You can use a B intake on an RB block with stuffing plates and gaskets but can't mill an RB intake narrow enough to fit a B block, not that such should occur on this swap.
Thanks for the reply. I understand the differences between B and RB blocks. B body Headman headers will not fit in the 65 Fury with a 440 - been there and there is no way to get the passenger side in due to the torsion bar. The driver side would take some "adjustment" with a hammer to some of the tubes to get it to clear the steering box. I have a set of stock exhaust manifolds for the 440 - but they are for a truck or motor home. The passenger side is a 3/4 dump and the driver side is a center dump. The passenger side works fine but the center dump on the driver side puts it against the steering box which would require grinding on the manifold and the steering box. I know that the 65 Fury III was available with a 383 "B" motor and I was looking for a pic or details on the driver side exhaust manifold for that specific year/car/motor. Mainly so I could see if it was similar to the normal driver side passenger car manifold that dumps in the rear at an angle. I did find a set of 383 Manifolds from a MOPAR in 66 - both are 3/4 dumps which I think will work on the 65? I purchased a B body driver side manifold with the rear dump and am now just waiting for it to show up to see if it will work. I'll post the results when it shows up.
Also discovered today that I will have to take about an inch out of the stock 65 Fury III drive line as the motor/trans using Shuamacher mounts sets back about an inch. Maybe the big block 727 trans is an inch longer than the 318 poly 727? I don't have the Poly trans to measure. I have scoured the internet looking for info on this swap. You would think it would be fairly straight forward due to the factory available 383 in 65. Any detail I have been able to find is fairly vague. Another issue we ran into is that the stock power steering pump wil not work with the 440 - mounts are way different but there has to be some brackets or pump out there that works with the 383? I can't find anything on this. I mocked up the Alternator and power steering pump that came with the 440 out of a motor home - alternator works fine but the pressure side fitting on the back of the power steering pump hits the Shuamacher driver side mount and will not allow the bottom - adjustment bolt to insert into the water pump. The mount bracket will have to be notched for this pump to work. The search for answers continues.
There were HiPerformance C Body manifolds produced from around 68 to about 72. I'm not sure what the casting numbers are right offhand, but could look them up. The Pass side was the same as B bodies and the left is C body specific. They have 2 1/2 outlets for the best performance. Look on ebay or get on Cbodydrydock.com want ads.
You will have to have exhaust made for these or purchase a TTI exhaust system-expensive but well worth the money in my opinion. You just have to tell them the manifold casting numbers and the car they go on and very close to a perfect fit. PM me for more info.
There are 2 left manifolds on Ebay right now. Type in C body exhaust manifolds. The earlier one is the 409 casting, it would look the best on your Fury.
Thanks for all the replies. I found one on EBay - it is not like the Hi Perf ones but it was from a Dodge Monaco and it fit nearly perfect. It's a little tight in the back at the steering shaft heat shield but it has plenty of clearance - did not have to grind, cut or hammer on anything. It was a little challenge to install it as the exhaust studs were stuck in the head so we unbolted the motor mount and raised the motor on the driver side about 2 inches. It almost bolted directly to the existing exhaust for the Poly.
Fired it off today and broke in the cam. Seems to run very good - should be driving it tomorrow! :thumbup:
