how full did you fill the radiator ? it needs to be an inch of so below the neck ?
what type of cap on the rad ? if you have a new cap thats designed for an overflow system then its going to puke coolant because its supposed to .
They are all designed to puke at high pressure reserve or not. Difference being that the cap for reserve tank equipped systems have a provision to allow the coolant to syphone back from the overflow tank to the radiator as the radiator cools causing a vacuum. The hose to the recovery tank MUST go to the bottom of the recovery tank either from the outside or from the top fed down to the base of the tank so that it is in coolant if it is puked into the tank.

hi first thing that comes to inde is your bottom rad hose is collapsing at hiway speed . make sure you have a spring inside the bottom <suction> hose . you can make one from a coat hanger wraped around a pipe to form it . let us know !

Difference being that the cap for reserve tank equipped systems have a provision to allow the coolant to syphone back from the overflow tank to the radiator as the radiator cools causing a vacuum. The hose to the recovery tank MUST go to the bottom of the recovery tank either from the outside or from the top fed down to the base of the tank so that it is in coolant if it is puked into the tank.
 The difference in caps is is a cap for the older  'overflow puke on the floor' systems only has one rubber gasket. The 'recovery' types have a dual gasket on the cap. For the old on the floor type containers the overflow tube goes in the top of the tank. Once it overflows, the coolant does not go back into the radiator. With the closed type recovery system, the radiator overflow tube enters the tank from the bottom. Sometimes there will be an additional; hose coming out of the top but that is just incase the tank gets to full. With the recovery system you can fill your radiator to the top when cold and then some. When the fluid expands it pushes past the cap and enters the recovery (overflow) tank thru the bottom. This keeps the system sealed from outside air. When the coolant cools down it contracts and is litterally 'sucked' back into the radiator. If you have a pre 71? car and want it to look stock but not puke on the floor you can get a plastic recovery tank from Summit etc, and mount it out of sight in a front wheel well, etc. I did this on my sig car and itis invisible and works like a champ.
