Cooling system question

[thunder550]

Here's my other ride too, my 01 Chevy Silverado. I had a 6.0L supercharged motor in it but it's broke, and I'm working on building a 408 for it that will eventually get a nice turbo setup, probably somewhere around 15 psi. I'll be shooting for the 700-800 hp range, and hopefully low 11's or so in the 1/4.

Once the truck is done and I recover from the huge financial drain, I want to put and LS1 or LS2 with a 6-speed into the Supra. I think that would be pretty badass.
