Which car is faster? A NASCAR Chevrolet Monte Carlo Stock Car or an IMSA Porsche 962?

I haven't watched NASCAR for a long, long time. That was back before they detuned the cars and started using restrictor plates. Wonder how they'd compare today!

Don't forget that Harry Hyde lowered the ride height of the Monte Carlo and did a few other things to it that did not meet NASCAR rules. The Porsche was at a disadvantage because of all the downforce it made, you have to wonder how fast the Porsche could have gone using Le Mans body work instead of IMSA bodywork. 

The test was done at an automotive test track that is designed as a banked high speed oval that is I believe 7 miles long for automotive manufactures to do high speed testing. 

Back to the down force that Monte Carlo would not come close to the downforce made by the Porsche, the Porsche would eat that Monte Carlo up on a road course. I remember reading a piece years ago where Harry Hyde talked about this run and all the things they did to the Monte Carlo that would not pass NASCAR rules. 

@john3976 - The run was conducted at the Transportation Research Center (TRC) in Ohio.

I purchased that issue when it came out, one of other interesting things of this apples to oranges test was the apple not meeting NASCAR rules because of all the changes Harry Hyde did to the car where the orange being the Porsche could have been transported directly to an IMSA race passed inspection and raced. 

It was an interesting read.
