Default ls1 408 build help

Hi, thanks for all input and comments. I have a 86 long bed square body. Bought a 6.0 ls (02) with 317 and planing to stroke it to a 408. Just recently bought my rotating assembly forged pistons. Need advice on my build shooting for 11:1 compression ratio and about 600 hp w/nitrous. On a budget and need input on the build cam spec and all. Also going to get the 317's ported,polished and milled to the 243 chamber. Any questions on build or need specs plz give comments and leave feedback. Thanks all
First build also.

If you already got your pistons you might be limited in CR, also is this a LS2? Where did the motor come from? Is it aluminum or a Iron LQ4/LQ9?

Post up what you bought already and what your block is and we can help you more.

It is a lq4 6.0 not a ls1 5.7. if it is a 02 it should be a aluminum headed motor correct.
