We own a 370. We own an X84 N55 (basically a heavier, less handling E91).
The Z is a high output NA, likes to be above 4K.
The N55 has far more torque under the curve and of course is tunable without much money for 3-5psi and 50/70 or so.
Equal drivers and traction I would expect a stock N55 to nose out a victory at the strip.
At the end of the day, its a juvenile pissing contest as anyone with a SBC will own either car and have far more money left over to treat the laaaa-dieeeees to a nice steak dinner.
Subjective note: The Z is far more fun to drive when the road isn't strait. Old tech and all, its still a solid chassis and responsive engine.
