I'd say 3/8, since that is the size vacuum cap I used to seal off the TB pipes when doing the TB bypass.

Griffin should know that info. I have an LT1-specific Griffin, and it has a factory-matching connection for the steam pipe. If you believe the factory manual, the stock radiator has a vapor/liquid separator behind that connection. I don’t know if the Griffin includes that detail.
