what rpm limit?

i have an 02 ls1 engine and t56 it has the following mods:
ported 853 heads
double valve springs and titanium retainers
crane 1.8:1 aluminium rockers
crane push rods
ls7 lifters
crane cam http://www.cranecams.com/product/car...detail&p=24249
alloy flywheel and under drive pulley
ls6 intake and ported oem tb
stock bottom end with katech rod bolts

I am going to use a stand alone ecu without the maf sensor and i am wondering what i sensible rpm limit would be obviously i know its my own choice but it would be interesting to hear what people think?

That cam says 6000 and 6600 for valve float, so stock limit 6000, or get a cam that will make power to 6700-6800 and use it because that cam is holding you back!
