It can vary a bit since some ls-1 cars can dyno in the 325rwhp range bone stock, while others bone stock will pull 300-310 range. So I would guess his about 340-350rwhp, but like I said it can vary alot.

If he gets a tune, he will add another 10-15 RWHP off a dyno tune.

I didnt know LS1's had "chips"....maybe he's talking about a tune??

LS1s don't have chips, you are right.
BTW who cares about horsepower at the crank. Are you racing engines or cars?? He's probably around 335hp to the wheels right now. A tune would help him reach 350ish.

A lot of people only care about horsepower at the motor. You tell someone around here...I have 350 rear wheel horsepower...they are like that's it...350 horse? If you tell them...yeah...my motor is 410 horse they would be like...ewwwww...ahhhhhhh...wow thats great. Different strokes for different folks.
Besides when your building a motor...you dyno it way before you drop it in the car so "crank" horsepower is just as useful as RWHP since its usually measured first.
