| Re: 1933 Buick model 86 exhaust manifold 1933 through 1935 80 series and 90 series use the same parts for the intake and exhaust manifolds.
The only difference between 33 and 34 & 35 is that the 34 and 35 center sections have fins on the inside back for more cooling.
I have an unmachined reproduction casting of the center section if you are interested. Machining is very difficult because of the different angles of the machined faces. It is also made without any provision to install the flapper. When I was doing research to make this center section, I was told that this was the first thing that caused a problem and was removed. My car runs good without the flapper. It has been from Long Beach, Ca. to Phoenix, L.B to Sacramento, and L. B. to Las Vegas without manifold problems.
This manifold has undersize openings so it can be machined to your end pieces after you clean up and true the end pieces. Let me know if you are interested. |
