Wow, that looks like an easy solution. One question though: On the other thread they made a big deal out of the fact the steam vent need to bleed into the low pressure side of the radiator thus why they installed a bung right below the cap.
Using this adapter where the hose goes into the top of the radiator would put it on the high pressure side. But you say they used things like this on some of the stock LS applications?
My steam vent is hooked into the cooling system down low near the top of the water pump via a T fitting. But they say it should hook where the steam can go to the highest part of the system.
