Running a 15lbs cap.
In the Holden book it says 253/308 uses 13lbs with thermo fully open at 202F
Chev 327 13lbs @212F
Chev 350 is 15lbs @217F
That seems pretty hot to me..
Is a 13lb lid the go or what?

Suppose the first stupid question is,I have noticed that no matter how hot the car gets it never sends any excess fluid to the over flow bottle.

Are you using a recovery cap? or a standard cap?

I'm using a factory UC recovery system with a recommended cap for it and it works a treat.
The std cap only has a gasket, the recovery cap has a large seal.

Main visible difference is the big seal in the cap itself and its got recovery stamped on the top, too hard

Standard cars run low pressure caps, race cars usually run higher pressure caps, 13pounds and up to compensate for the higher heat generation, a trade off from the higher out put of the motor.
The higher the rating of the cap the higher the temp u can run before you loose water.
