Yeah I was just a little confused because he said ZR1 Camaro, so wasn't sure if he meant ZR1 Corvette, or ZL1 Camaro .

Yep, ensure you get the right feeder pump, either OEM or an Aeromotive that's compatible with a pulse width modulation signal. Some magazines got an LT1 and LT4 started without a PWM pump (just used a regular instead) but couldn't get it running right afterwards.
