Same track, basically same conditions my 99 Z28 and 95 Mustang GTS.
1. I am an average driver
2. I removed driver differences by being the driver on both cars.
Yes the Mustang beat the Z but at a ton of work to do so.
Bolt on a set of Drag Radials to the Z, the results would change again.
Take it or leave it as you will. This is about the most factual and realistic test I can imagine.
same track, controlled enviroment.
same driver.
same weather conditions.
I just think that so often it comes down to driver.
Anyway, who cares. All these ifs and what ifs. I only run mine for personal satisfaction. I have never street raced. I choose not to modify my LS1. The 5.0 is easier to work with to a point, but not really that much for an experieced gear head. Mod for mod the LS1 will win everytime.
I love the sound an muscular look of the Stang, the blvd bruiser. The LS1 is a fierce highway car. Tell me of a stock 5.0 that easily runs up to 160 on an open road, they closest car was the 95 Cobra R.
