Several Holley carbs (mostly Ricer type 2 bbls) used a water choke housing to SLOWLY cause the
choke to "come off" on cold starts.

I looked at the same deal for a cross ram project.

I thought the heat would be much better than a cold manifold on the initial first few minutes of running. You actually get heat into the heater pretty quickly when the thermostat is closed and the only water flow is through the heater core and back to the pump for another cycle.

My deal was different though:

I was going to use a oil cooler filer housing (like they use on trucks) that normally uses
water to cool the oil.

I was going to pump the water from the back of the heads, through the oil cooler, (cooling the oil, but also heating the water up very quickly), and then from the oil cooler going to the intake, and finally on to the water crosss-over.

This way I would do two jobs vs just one.

Once the intake was warm, I was going to use an old "pellet" vacuum switch off an Ford Escort
to turn off the water to the intake and send it directly to the cross-over. If the intake cooled down too much the "pellet" vacuum switch would turn the system on again.

All of the pieces could be hidden and no one would have been the wiser.

ps I don't have a heater in my car (heater delete) so the heater deal was out.
