Took my buddy's grand national to the track a few weeks back for some testing. The camaro in the right lane is one we've been working on and has a stock 6.0/4l80e setup with a harris plate kit The GN was doing 11.9's on low boost and the camaro went 12.0's on a 75 shot.

The GN took off smooth and quick. Two nice cars man. 69 camaro and a Grand National are two of my favorite cars.
