no offense man but have you tried searching? there are literally hundreds of threads on this. with bolt ons only you might see 5hp on an ls1. with a cam 10-15 is the typical gain over an ls6 and from there the gap just gets wider and wider as you get more wild with mods

seems a majority of ls1 builds gain toward the 8-12hp range...some might gain more if the engine really needs it (strong head/cam cars or larger cubic inch builds)

Went from an SLP LS6 intake on my '98 Z28 swapped stock internal LS6 longblock to the FAST 92mm and NW 92mm TB and picked up right at 15 rwhp. I do pretty much have all the bolt-ons, but my LS6 is bone stock internally.

It was a lot of money to get those extra 15 ponies ($1K!), but I wanted to get over the 400 rhwp mark without opening up the motor and it did what I hoped and I put down 400.1 rwhp up from from 385.6 rwhp.
