Default 6.0, DIY Ported 317's, Custom Cam..... ?

OK so I've got a fresh stock bore 6.0 LQ9. I'm in the middle of DIY porting some 317 heads because this is a super budget build. The heads will be decked .030" to get the compression to around 10.8:1 or so. I'm no stranger to head porting so I'm looking at flow numbers in the 285-295 range @ .600" lift for the intake, possibly around 220-230cfm for the exhaust.

Engine will be going into my 2000 NBS Tahoe.

6.0 LQ9, Shortblock
317 Heads, diy ported, decked, 918 springs, stock 2.0/1.56 valves
LS2 GM .051 MLS Head Gaskets
TBSS Intake Manifold
30lb Injectors
90mm TB
85mm MAF
Custom 4" Intake Piping
228/230 .587"/.592" on a 112LSA
LS7 Lifters
Stock Rockers
1-7/8" Headers
T56 w/Monster LT1-S Twin Disk


So, what do you all think it might do? I'm hoping for anything over 400rwhp but it's a fairly conservative cam. I chose this since it's going into a 5000lb Tahoe and will be my daily driver.

Reminds me of my setup now that I'm losing the turbo kit. Forged 383, ported 317's, 226/222; except I'm down around 9.0:1. I'm hoping for anything over 400rwhp too. I think its doable, especially for you since you're bumping compression.
