Would a 1/2" or 3/4" hot water tube running under the runner transfer enough heat to work. Would it be better to run it through the log? I am converting an Offenhauser 3x1 L6 manifold to a 2X1 for an L4. It had exhaust heat under the center carb.
When I cut the manifold apart today I was able to see the exhaust heat runners that are full length and under all three carb bases. Do you think I can get enough hot water through them to work? It wouldn't be hard to make the change.
