I'm building a 94z28 to take to the track and I'm stripping a lot of stuff off. I'm not running heat or ac. I'm now down to hooking up my water hoses and blocking off nipples on radiator and water pump that I'm not using but what do I need to do with the vent line that runs from the rear of the heads? Do I just bypass the tb and run straight back to the radiator or just cap it off as well. I'm thinking run back to the radiator so air pockets or pressure won't form but want to ask someone that's been there done that. Thanks in advance. Next I'm off to removing the abs opinions welcome.

 

What you are referring to is known as the throttle body bypass. Countless people have done this as it is a very common mod. All you do is take the TB out of the loop of the coolant, running the steam pipe hose directly to the radiator. Don't cap it off.
