Stock cams, just wondering if these injectors will be too big?
I'm assuming Corey tuned the motor as well and he's one of the best. The real issue w larger injectors involves control of the PW at idle. Too big an injector and a smooth idle becomes problematic.
There are big displacement motors running on stock injectors although that doesn't mean they couldn't use more fuel. A determining factor is assessing the injector duty cycle at WOT. Is the injector going "static" in order to provide the proper amount of fuel at WOT?
Rule of thumb is you'd like to be at ~85% duty cycle.
