My thoughts---

round 1- Z06 on motor> SS on motor
round 2- SS on bottle >Z06 on motor

Just like someone said above. The Z is lighter, more aero, and on the bottle! The Z from the factory is putting @430-440 at the wheel. Add the LT's for another 15-20rwhp EASY!!! If he was running a 150 shot as I would assume with dual bottles that would put him @575-600rwhp/625-650rwtq without sweating.

If that was a stock 346ci SS w/ cam, bolt ons, and bottle- 125-150 shot it just doesnt make since. Let's say 525rwhp on bottle out of the SS, and it weighs 500-600 lbs heavier from a highway roll.

Just my .02 cents on the vid. Would like to hear the facts from the two owners.
