1931 V12 370A PLEASE HELP!!!

Hi,

Does anybody know where I could buy a new or restored pair of intake manifolds for a 1931 V12 370A?

My problem is that the manifolds get extremely hot when the car runs. Valve and ignition timing is dead on and I have overhauled the Carbs. I think the problem may lie with the previous owner who restored the car, I fear he may have had the inside of the manifolds shot blasted, thus wearing down the
thickness of the inner metal.

Any thoughts??

Many Thanks

Philip

Philip, What I know about a V12 could be written on the head of a pin. But I do know that the intake manifold should not get hot. IM not saying that they cant get hot from "heat-soak" from the engine when it gets up to operating temperture, But, experance tells me no. I use to work on KC97 APUs and the way to adjust the carbs was to grab-hold of the intake manifold and when it was at it coldest point, stop adjusting the fuel/air mixture because the carb. was adjusted properley. As an aside, I dont think that the previous owner damaged the manifolds by having them bead-blasted. Philip, You can check what I have said by feeling the manifolds right after start-up to see if they are cold and check them every few minutes to see if they are getting hot.Use a "space-thermometer" if you can find one and see if the intake is the same temperture as the engine.
If it is, I dont know what to tell you.

Good Luck,JIM

Hi Jim,

Thanks for your reply, I think the problem is more than just heat transfer from the engine though.

Hopefully somebody out there will have an idea of where the problem lies

Thanks again,

Philip
