Im still new to alot of componenets on the LT1. What is the point of a 'throttle body bypass' and what exactly does it improve? (if it does improve anything)

 

Keeps the throttle body cooler, reducing the transfer of heat to the incoming air. Colder air is denser, can burn more fuel, make more power..... about 6HP according to this dyno test:

Just to add to Injuneer's response.

In stock configuration, hot coolant is run through the throttle body. The throttle body bypass removes that path of hot fluid through the throttle body so no heat from the coolant is transferred to the incoming air, as was said.

I believe the purpose of running the hot coolant through the thottle body is to prevent sticking throttle blades on cold start-up.

The purpose of running the coolant through the throttle body was to prevent throttle body "icing" during extreme cold weather operation. The venturi effect of air passing through the throttle body bores can cause a drop in air temperature, sufficient to allow any moisture in the air to form ice on the blades, possibly causing them to stick.

Unless you live north of the Arctic Circle, this doesn't seem to be a problem.

 

Unless you have a block heater, the coolant is going to be the same temperature as the rest of the engine on cold startup.
