340 intake manifold

I believe that you need a cap for the choke stove so it does not leak exhaust gas.

You should be able to mount an electric (stock) temp sensor and a mechanical one on the aftermarket manifolds with more holes by the thermostat housing. You may need to get a bushing to adapt it to one or the other temp sensors.

Also make sure that there are bosses in the rear of the manifold to mount the coil to, or you will have to relocate it and get a longer coil wire.
