Re: [Amc-list] WHat year 258's get water intake? Real world advantage?

[Frank Swygert <farna@xxxxxxx>]

Flow? Remember, you did the calcs as to how much a 196 would flow... not much! Now with that little 1-1/4" carb it really doesn't need much! The only reason I can think of for the heat tube was to stabilize the temp inside the intake, just as you mentioned that was the real reason for water heating the intake on later years. My feeling is that it was removed from the 2V model because it would block too much flow. 

I drove the 1V and 2V in cold weather in Idaho, 83-87. The engine ran fine, didn't take too long to warm up either. My J-10 takes a good 10 minutes in freezing weather with the water heated Clifford. I don't recall the Rambler taking that long. I drove it through a blizzard (2V model... put a 2V on about a year after I got the car) when I moved from Idaho, towing a utility trailer. We ended up staying at some hotel in the mountains halfway between the continental divide and Cheyenne, Wyoming. When we got up the next morning it was 5° -- at 9 am in full sunlight! The battery wouldn't turn the engine over, but that was the only problem I had. Had the generator, and had run the lights for several hours through the blizzard at 40-45 mph, plus the trailer lights. Guess the trailer lights and the cold put a strain on the battery and/or gen.

Anyone here run the 195.6 OHV (or L-head, for that matter) in really
cold weather? I would imagine it does pretty well with that intake
design. Of course power and revs are a joke, but hey.

I've got a 2 bbl on mine, but I have a couple of 1 bbl plates here,
one with the water heated tube. It's hard to imagine that this was
added, to an "intake" that's a 1" groove in cast iron right over the
exhaust valves.

The funniest part is how it blocks half the area of the carb port, as
if there's a lot of flow capability to spare.

Clearly, drivability and economy was the goal. Flow-wise, what a mess!
