RE: I run my blocked crossovers in Minneapolis.

I don't think the cross over will help that much with icing. The only time that I know for sure I experienced this was as it was begining to warm up after a snow/rain storm, with the temp at about 35. As the roads began to dry out I was driving reasonably fast. The engine began to run rough and I gave it more throttle (I'm just about the smartest guy I know, if it doesn't seem to be running right, just give it more gas). It coughed back through the carb and the throttle plate wouldn't go back to the idle position. I pulled over and stopped and the engine died. I got out and looked into the carb and there was ice built up on the low pressure side of the front venturis and the bottom of the fuel discharge tube booster venturis. The ring of ice that had been on the driver side booster had come off and had blocked the throttle plate partially open. As I stood there trying to figure out what to do, the engine heat melted the ice and the water ran down into the motor. Problem solved, right? So I jumped back in and started it up and headed down the road (you might be asking yourself, did he say the water ran down into the engine? I told you I was smart). I got about ten miles down the road and the same thing happened again. This time I blocked the throttle open and sat back and took a little nap and let time and temp do the work.

There is a point to this long winded story. The victim car is a 68 500KR which has ram air. The engine was stock, didn't have the cross over blocked but did have the 0.38" phenolic spacer under the carb and cool very humid air dumped straight onto the carb. Cross over heat didn't do anything to prevent carb icing under these circumstances and with this particular installation I don't believe it ever would. In fact, I think I agree with Shoe, if it will start when it's cold, you may not be able to tell whether you got cross over heat or not. By the way, did you ever tear apart an FE and find the cross over completely blocked with carbon? So have I. That may be what cross overs do best, is collect gunk.
This thread, so far...
