Your setup is almost exactly like mine. I had a small run with a C7 a while back. I assume it was stock. From a 60 mph roll I was definitely pulling. All things being equal you should have the edge

What did your car dyno and run in the 1/4???? My goal is mid 11's and 120-122 traps

At a raceweight of about 3850 lbs my best trap was 120 mph. That was on my big 17x11 street wheels. A drag setup alone would help a lot. You should have no problem

I am not a huge racer but I prefer rolls. I am currently running street tires, 275/40/ 17's, but will be switching to drag radials soon.

From I roll I'd be blown away if you didn't win. As long as you don't spin of course

Stock C7 is a 12.2 @ 116 car. You should pull it easy.

They launch so hard from a dig; they seem faster than a 12.2 car.
