splitting the manifold on a 230

[ericswanger]

Group,

I have a 50 Wayfarer coupe (230 flathead) that I have owned a couple of years now (resurrected from WV) and putting it back together and updating using all period correct speed and custom add-ons.  Not to worry, it's all bolt-on and I'm not cutting anything!  I just finished putting in an overdrive and am now looking to split the manifold on it.  Any quick tips on splitting the manifold, does anybody have a split manifold out there or does anybody have a stock manifold for cheap that I could use to cut the outlet off of? 

 

I've attached a photo of the Wayfarer for discussion.

 

Great car, a ton of fun to drive.  Fluid drive with overdrive.  Oh yeah!

 

Thanks

PM Tim Kingsbury, he/they AoK Racing, will make yours into a split exhaust manifold, think it is $175 USD. It is done in Fertigs Pa, by George Asche, your intake can be done for duals too, for around the same price, he also makes linkages for dual and tri carb set-ups....good luck

Forum member Moose also makes tubing style split intakes and exhausts.  and forum member Old Daddy (rustyhope.com) also does spliting.

Moose does nice work, dual/dual setup, $400 approximate price, but sounds like OP wants his stock converted.

Charlie Akers does stock conversions, and also sells a 2nd exhaust outlets for the do it your selfer.

Asche, can make tru split exhaust halves, or in the whole form the exhaust manifold is truly divided, not just and 2nd dump.

Any of these directions should be good to go........

very difficult to convert an original manifold. Not in concept   just doing it.  One,  they are very hard / brittle by now. Also cast is extremely hard to weld without cracks.

I did one and had a pro weld it for me.  Never even installed it as the "cracks" started.    My thought if I try again is to have it annealed first , to take some of the hardness out. But then your concerns go to warping.    Thus   look for options

Charlie a member? I would like stock ones

Yes Charlie is aka Oldaddy http://rustyhope.com/site/ or call George Asche, the Chrysler Flathead Guru @814-354-2621

Eric, have attached a couple of pics of the setup that I intended to use on my 41 Plymouth coupe.........there are at least 3 different exhaust manifolds used by Plymouth on the 23" engine......one that has the exhaust outlet between # 2 & 3, another with the outlet between 5 & 6 and a third with the outlet after # 6.....make sense?.......my stock manifold was the 2nd type so I found another manifold that was the same plus one that was the 1st type, cut the manifolds and took the front of one and the rear of the other(you following me?.......lol) to a local blacksmith and had him properly weld the ends........dada!!.........a twin outlet split exhaust......I did it this way because my car is a factory RHD & the steering box would foul the front Fenton style manifold and the pedals follow thru would hit the rear Fenton manifold if I used Fentons.......lol.....so I had to use stock style modified manifolds.......anyway I dunno if showing these pics and this info helps but there you go.....lol......I ended up selling both the car and engine before I installed it but it was expected to work.........regards, andyd

Now there is another good idea, Andy.

Did you notice a nice boost in power when you added everything onto this engine?

What engine are/were you running, 201,218, 230?

Won't be long and going dual/dual on my Fargo truck, can hardly wait to see how difference it makes.......

A lot of great ideas!  My car has the outlet behind #6. I can get my hands on a 5-6 manifold as well.  I had thought about seeing if there was a 2-3 outlet intake because what Andy did makes perfectly good sense and gives you a true dual.  The bolt-on kit that rustyhope has seems to be the most straight forward and least invasive way to get the dual.  I used a guy years ago to split Chevy manifolds and also to repair head cracks on British cars.  He did it proper by heating to red in and induction furnace and then welded it and I never had a single problem.  He has gone on though, and the owners now don't follow the proper heating procedure and the results therefore leave something to be desired!

 

What is everybody's thoughts on mufflers?  Looking to get that mellow throaty burble!

Just a FYI, George Asche, can make yours a true split divided set, either with the centre heatriser section, or 2 halves your choice, super quality experienced work, George is 84 YO, and is still making these and building engines.

Before you make a decision, PM Tim Kingsbury, he and George can give you a price and what to expect for turn around time, he rebuilds the carbs and makes super quality carb linkages too, if you are going the dual carb route.

As mentioned, you can go this route, or Rusty Hope, or do it yourself, but the price to have say George do it, is quite reasonable, as I am sure the others are too..
