LS1 Intake, what would it cost me? I am considering changing my 5.3 to the ls1 intake. How much should I expect to give for the ls1 intake, fuel rails, injectors, and TB?

Parish made 1000rwhp/1000rwtq with a 5.3 intake on a twin turbo 408 and ultimately went bottom 10's at 140mph or so in a 5,000lb+ truck.... AWD Sierra 1500 pickup with 4L80E..... so it isn't that restrictive.
If you don't have height issues with the hood.... maybe just stick with what you have. He also put a 5.3/Z06 cam/valvesprings with T70 turbo in a Ford Fairmont and went 9's at nearly 140mph.
If you have the money do an LS6 intake as they flow more.

Even those aren't really worth it for the hassle of the swap and the money. Most the truck guys stopped the swap years ago as the gains didn't cover the costs.

The LS1 and truck are about the same
Note: the SSR90 intake listed is the truck LS2 intake it flow similar to the LS6.

I have heard of/seen some people clearance the waterpump by heating the aluminum where the steel insert is pressed in and been able to rotate the steel piece out of the way. I've also seen precision denting to make it work.

You can just cut the alt bracket a little and move the idler pulley via a relocation kit of make your own.
You can heat and bend the tube or swap to the L92 truck pump it has a 45* outlet

i would also like to add...
is that you don't necessarily need a custom relocation bracket.
what you can do is buy a longer bolt (6 inches long 10mm x 1.5 threads) for the idler pulley, space it out with washers untill it lines up with the rest of accessories. you'll be placing that bolt and pulley in the very top bolt hole on the p/s and alt. bracket. like this...

Here is how i modified my truck waterpump to work with the car style intake ,All i did was rotate the outlet and put a small dent in it for the stud to clear it ..... its been working great ever since. you can also see that I took the stock alternator/power steering bracket and cut it down so that it only holds the Alternator now instead of both.
