I'd have to go with Warren here. I drove my G for years with no carb heat - all heat pipes were off when I bought it, maybe because it lived its life in San Diego . Made for a temperamental car - like Warren describes - especially below 70 degrees or so. And with a ram manifold "full operating temp" doesn't help because of the location of the carbs. This mod might be okay if you just need to drive in and out of a trailer, or over the auction block, but if you actually drive your car, you'll hate yourself. Andy Mikonis Headed for 70*F in Chicago.
