Howdy all I am the guy working on the OPTIless LT1 in a K1500, and I am stuck on the water pump and could use some advice, the stock Camaro/Firebird WP has 2 5/8 hard lines coming out of the front of them. plus the whole setup has to many water lines for me to just start blocking them blindly. I will have the steam line from the back of the heads, the Throttle body heater lines, the cab heater, and I can proly use the return line in the radiator for some of this. any ideas as to what I need to keep and what I can tap and plug (on the Water pump) or any thing else would be greatly appreciated.

P,S, I am not sure whether I will use the stock truck radiator or purchase an LT1 radiator, for this cross breed machine.

America, Love her or get the He!! out

 

I did an LT1 conversion in a 1989 C1500
You can plug the driver side 5/8 outlet in the front. It was originally used for an oil cooler in the LT1 engines.
