Hey guys,
I'm thinking about doing the !EGR mod on my ZZ4-cammed TPI 355. I remember the LT4 motors came without EGR from the factory since the cam had enough overlap, it was kinda like a built-in EGR. I think the ZZ4 cam is a touch bigger than the stock LT4 cam so would it hurt to !EGR? Any pros or cons with getting rid of it? I have Collector registration on the car, so no worries about emissions.
