LS1 Block info
Just think about what set-up you want to run on your car and just use that idea for how your going to mod it now.

Its not a 413 like you want, but it is a nice replacement for a high mileage engine. And im sure they can get you a sweet deal if you get a long block as well, but i know that even $3000 isn't cheap.
