Well im at the point now that I believe my ZZ9 cam is holding me back : current times with this cam 12.58 @ 107
ZZ-9
Intake Exhaust Advertised duration 282 287
Duration at .050 212 226
Gross lift .483 .520
Lobe separation 112

In my quest for more I called compcams and they suggested this custom grind:
lift duration lsa
567/585 224/236 112

Does anybody think I will run into any tuning problems or horrible
drivability?

Thanks for any help.

 

Shouldn't be too bad,but at low rpms your engine will show limited repeatablity due to the big duration. (ie the the ecm will get somewhat confused). If it doesn't set up for you just make the idle always open loop.
