Default Injector size
I recently had my 01 Z06 tuned and we could only get the injector duty cycle down to 88% when it was 100%. I'm about to do a cam and small bolt-ons here very soon and am wondering how well 36# injectors will work for me.

Also what size are my stock injectors?

ZO6 's are 28.8 lbs.

36 lbs should work with cam etc. They should be good to about 525 engine HP without overtaxing duty cycle.

36# Ford injectors? Ford rates them at 43 lb fuel pressure. At our 58 psi, they're more like 42#
