Exhaust manifold for model B engine
Exhaust manifold for model B engine?
Does anybody know if a 30-31 model a exhaust manifold will fit on a model B motor? Mine is almost split in half I may need to get it welded or find a new one. Thanks again Daba |

Re: Exhaust manifold for model B engine
The Model B exhaust manifold will bolt right on to a Model A motor. The problem comes from the fact that the Model B manifold exhaust pipe goes down at about 45 degrees while the Model A goes straight down. What vehicle do you have?

If in a Model A Chassis, use a Model A Manifold which are available new. If in a '32 chassis, only a '32 Model B manifold will work. These are not available new but if you need one, I have a good used one. If it is in a 33-34 Chassis, use a Model A manifold, they are the same as '33-'34. Chris W. |

Re: Exhaust manifold for model B engine
I have a Model 31 A with a model B engine the exhaust manifold is cracked pretty good around cylinder three, I may try to get it welded today just wondering if a Model A would fit as I believe that’s what’s in there. Thanks again

Re: Exhaust manifold for model B engine
They are interchangeable except for the outlet angle. Id advise against trying to weld it. I probably have several if you care to trek to albany. Or check with tams for a used one

Re: Exhaust manifold for model B engine
I wouldn't waste your time trying to weld it, new or used manifolds are inexpensive! If you're just wanting to weld for practice, have fun
