Z06 springs... as in LS6 springs??? if so - get some REAL springs on that bad boy and let her rip.

every car is a little different.

i've seen 6spd cars with cams in the 230's duration make 380 rwhp, and automatic cars make 400rwhp with a 228 cam.

let the timeslips do the talking.

You need to ditch those LS6 springs and put some much better springs on there or you will be in expensive trouble very soon.

If I may make a suggestion,

Get dual springs and this grind (custom)
