There's a couple of websites dedicated to this swap and explains exactly what's needed etc. Theyre are also companies on ebay and on the net that sell everything needed as a kit persey. You can reuse the radiator and fuel system I believe.

You'll need a CAI setup for an LT1 unless you want to go to a taller hood.

quite a few doing this swap these days, EXCESSIVE is member here and has done it, he could give you some advice, think he come across a once in a lifetime engine deal though. It's all possible just comes at a hefty price.

I'd say save your $$ and stroke your LT1, or just buy an LS1 fbody and start over, but I'm partial to being an underdog LT1'er
