Hey guys, I'll be running a new setup soon and was wondering what youd think Id be putting to the wheels and new track times. Thanks for any guesses. I ran a 13.8 @ 98mph before heads, intake, and with old cam in sig. New setup will be:

08 Silverado CC
5.3L 11.0:1 compression
PRC 2.5 5.3 milled 60cc
Cometic .040" head gaskets
FAST LSXRT 102 intake
LS7 tb
EPS 227/230 .614/.609 114LSA+2 advance
K&N cai
OBX lts
SLP pulley
PB lvl 2
Circle D stage 2 258mm 3c
3.73s
Wheatley 93 octane tune

 

380-390rwhp, 13.13@103

 

Close to what i was think for the 1/4 times, might have to put some 4.30s in and try to break into a 12.9 lol.

 

Any other guesses?

 

I wouldn't be surprised if it did 400+, I've seen it done with less...

 

I'd guess 403hp/385tq and maybe a 13.0 being your in a ccsb
