I would first try to speak/type a little more fluently in english. There are people on here that will definately be able or wanting to help but it can be hard not speaking the same language.

Heads, cam, intake and exhaust are probably the cheapest route. SLPOnline.com has some cost effective combinations, and many of the sponsors on this site can help. The L92 heads are popular. Is this engine going in the pictured Impala?
you can get 600 engine horsepower but you are not going to see that N/A on a ls motor that you would like to drive on the streets. 500 seems to be the mark people are shooting for and it is very hard to do N/A- you better have big pockets.
Not if you would shoot for a 450+ build then would spray it then yes 600 would be achievable.

600 is possible with a 408 but it would be a nasty setup. Not street friendly and a solid roller. 520-545 would be a better goal n/a with that lq9. Have it bored .030 over and throw a 4" stroke crank in there for your 408

i think you could do it with a cathedral port setup reasonably. do whatever it takes to achieve 11.5:1 with the stock lq4 shortblock. clean up and mill some 243s or whatever, flycut & put a 250* duration cam in it with a ported/portmatched vic jr - i bet you'd come close with a healthy exhaust setup. how long it would live on stock internals @ 7400 rpm is a different story haha.
