1938 caterpillar r4

I don't know if CATMAN makes a manifold for that?
He is over on the RIF forum.

I know there is a R4 in Davison mi for parts, engine rebuilt, i believe it had a good manifold, or you could make a intake if your not concerned about it being authentic, I built one for my gas 40

contact me if you want to get in touch with the owner of the R4, last time I saw it was 3 years ago, the engine was sitting the floor in front of machine, it was rebuilt by a machinest so it was likely well done

The pic you requested, the intake in 1 1/2 inch pipe and the outer shell for the heat exchanger is 3 inch, the fittings are weld bend brand
