What intercooler pump are you planning to use Jared for your LT4 engine? I did a lot of research in that regard as I'm running a LS9 engine in my next build. The worst flowing one you could go with is the most popular Bosch pump.
I’m using the factory z06 pump. I have read various info regarding the pump. I was comfortable using the OEM pump. I am keeping everything in the rear of the car to keep the lines not much longer then originally designed for the front engine cars.
