Default LS1 Build-Up... Need some Info

Hey All...

I know some of these questions may be stupid but I need some help.

I'm building an LS1 for my 35th and need to know the fallowing...

What's the bore on a stock LS1?

What's the Stroke?

What's the Rod Length?

Etc.. Just basically anything pertinent to buiding the bottom end on my LS1...

I've already got a set of Lunati Pro-Billet Rods that are 6.250" in length..

What Pistons do I need to use for this?

Also.. I'm wanting to stay close to stock displacement and be able to hit this motor with a good shot of nitrous.

Thanx for any help!

Stock bore = 3.903 inches
stock stroke = 3.62 inches

If I were doing this I'd replace the rod bolts with ARPs and install a forged crank and pistons.
