Same torque?

I think this is getting a bit out of control here.

I'm just trying to figure out which car has the advantage in a drag race and roll type situation.

He didn't say he is starting at the top of 4th....

You first need to define the race specifics. Simply saying drag or roll is not enough. From what speed to what speed and/or distance from start to finish are just the basics to define an acceleration contest. Then the racing surface and tires allowed are also critical to the outcome.

Once you define the rules, only then can the differences in the cars competing be roughly guesstimated as to which has an advantage.

What you mean? It shouldn't be this difficult of a scenario.

I know a 650whp should be faster than 650whp Terminator in a straight line. Drag race or roll race.

I'm wondering how a cam only, supercharged C6 Coupe does against a heads/cam/intake supercharged C6Z. They're similar cars but they're pretty different. The LS7 is a better motor but it'll be making almost 60whp less.

I used same whp in my question because it'll be much easier to answer.

"The C6Z will win because..."
"The Coupe will win because..."
"The cars are similar enough to where it doesn't matter."

The real issue with arm chair racing is that we dont know everything. IF we knew HP curve at each RPM, and proper gear ratio...assuming your tires arent slipping everywhere... then you just take the HP curve (at RPM) and see how much effective HP you are putting to the ground over the entire race.

The problem with this is that one of the two hypothetical cars may be making more mid-range power (mid range as in not peak hp but within your used powerband of 4-6.5K) but the same peak power. That would make it seem like they are both in the same power range but during a race, it would be faster.
