Default HP numbers LS3

About how much WHP am I looking at with a Breathless Performance Vortex C/A intake, Doug Thorley Headers through stock xpipe and npp mufflers, MSD 8.5mm wires and NGK TR55s...and a tune of course.

390 plus or minus, depending on the dyno, tuner, and DA.

Don't expect miracles for the minimal mods. Most of the gain will be the tune.

400-415

I got 419/414 with an Airaid intake, 1 3/4" LG LTs (catted with their X-pipe and 3" to the NPPs), 160 T-stat and a tune

I'd throw in a 160* T-stat before he tunes it

I do have a 160 degree tstat forgot that I did that a couple months back. I am probably going to add a vmax throttle body and maybe some loudmouths before the tune. My goal would b about 425 or so then. Thanks for the input your setup isn't far from what I have now so I should be close to that number.
