Swap Ls1, what kind of power am i looking at?
 

I am getting close to starting my Ls1 T56 combo in my swap project. I was wondering what kinda of hp you all think I'll be making with the mods I have currently. They are:
2001 Ls1
stock MAF, custom smooth pipe intake w/ k&n or similar filter
1 7/8" custom headers 2 into 1 - 3" pipe with sweet thunder muffler
Summit underdrive crank pulley running only an alternator
Meizere electric water pump
Summit fuel rails and way more than enough fuel pump to support anything I'll have (A1000 aeromotive pump)
basic tune to eleminate emissions, anti-theft, skip shift etc.
Anybody have a guess with the above mods? I am just curious. I'll need to get tuned eventually but have a cam in mind first to roughen up my idle and up my hp.

350-360ish rwhp since you will have minimun assoc's. Make sure your fuel pump and injectors don't flow so much that they flood the motor tho. Get what you will need for the parts you will have.

I would say around 350ish.

I'll go with around 360
