Yes, Interesting thought.
Hmm.  Not sure I want to trust my 40 year old overflow tank to system
pressure cycles for the 1st time now.  Going to need an overflow tank anyway
to avoid driving over system puke at the track.
Think I'm just going to replace my swirl with a stainless one this time.
Thanks though.  Very cool idea I'm going to think about more.

I recommend that you update your cooling system.  Get rid of the Swirl Tank.

Route the coolant exiting the pipe off the thermostat housing to the lower 
pipe.  Braze a fitting on the pipe exiting the thermostat housing to allow a

1/4" line to go into your overflow tank at a level higher than the exit from

the thermostat pipe. You will need to add a fitting toward the top of the 
overflow tank to accept this line. This will allow the air to naturally 
migrate to the tank.

Connect the outlet on the bottom of the overflow tank to one of the intake 
fittings on your waterpump. This will be a 3/8" to 1/2" line.

Add a pressure cap of 12lbs or more to your previous overflow tank that is 
now your fill tank.

You now not only have an updated less restrictive cooling system with your 
pressure cap on the low pressure side of your coolant system, but, more 
money in your pocket.
