Default highest 93 octane compression ratio....

If you have ran over 11.0:1 compression ratio, please check in and list your CR and cam specs duration, LSA and lift.

Setup 1:
LS6 heads 11.1:1 Cr
230/230 .575 114lsa
no knock @ 29 degrees

Setup 2:
4.8 CNC stage 2 TEA heads 11.5:1
230/230 .575 110lsa && 232/238 .595/.605 111lsa
no knock @ 29 degrees

Setup 3:
4.8 CNC Stage 2+ TEA heads northward of 11.5 :)
232/238 XER 111 lsa
waiting to be dynoed

I am really interested to see if an all aluminum motor can handle high compression alittle easier than the older iron counterparts.
Phillip

BTW.....over 12.0:1 and daily driven :reddevil
