Default What power number should I expect?

I would love to hit 420whp

My plan is
Streetsweeper HT cam
http://www.flowtechinduction.com/fti...r-ht-camshaft/

Ls6 or fast 78 intake ( i have the ability to get either one for 350.00)
BTR Valvetrain

stock or handed ported 243/799 heads. milled .010. (could I mill with that cam?)

Texas speed longtubes, no cats, xpipe, stock mufflers for now.

CAI

Tune.

What would you guys say I should expect from those mods?

I had a 228R in a previous car and loved it for my DD. I never take my car to the track so driveability is huge for me. but I always felt like I could have been ok with a lil bigger than my 228 but not much

I made 380 on a 228 with stock ls1 intake, stock 853 heads and a rich tune..

Seems like 400whp would be low for that setup

We hand ported a set of 243s, milled them I think .025, stock gasket, and made 450 420 thru a 9 inch and a steal driveshaft with a stock ls6 intake.

Same cam made 415 400 in my old Z06 cam only.

It may not be a dyno queen cam, but it will hurt some feelings on the track and street.

My setup will be very similar to this


with different heads and no cats. should I be running bigger than a 78mm intake with this setup though?
