If you have the money, going larger cubes is always your best bet. 402/8 is a great idea.
Edit : You dont HAVE to use a LS2 block. You can save some money (and add some wight) by going with a LQ series Iron block.

Plus the ls2 has some differences like cam position sensor (and some other small things) that you wouldn't have to worry about changing if you went with an lq4 or 9... Plus like said, you can go bigger cubes with the iron blocks

Iron vs alluminum
Why can you go bigger with an iron block? Also would my headers fit an ls2 an transmission 4l60

The iron block is heavier (about 85 lbs heavier) but stronger than the aluminum block so you can bore it out farther and not have to worry aboutthe block itself flexing and coming apart. If I am correct the ls2 is the only motor that has the cam sensor in the timimg cover(all others have it in the back of the block) so ls2 take its own cam and no others. The blocks externally are prety much the same and headers, heads, trannies can all bolt right up

ls2 iron block
Is the ls2 iron block just considered an ls2 iron block? or is it something like lq???? I`m really only familar with my ls1 but want to inquire about a 408ci build

For a really good writeup, lok in the stickies in this section and read "ls1 info" should answer a lot of your questions
