Default LS1/6 Intake onto a 5.3

Hey Everyone.

I just did a search, and nothing really answered my question.

Ive got a 5.3 Here that im planning on swapping into my '89 iroc.

Now, im aware of power differences, and im told an LS1 intake will best suite the 5.3 over a Fast intake or such.

ANYWAYS,

What is needed to swap the intake?

Can i re-use my injectors?
Fuel Rails?

Planning on swapping the TB to a cable one from the fly-by.

Kinda off to the side, but does anyone know the stock 5.3 injector size?

Thanks for your help!!!!

Sheldon
