Back in the lat 80's a buddy bought a 73 GA that was a mild custom. It was lowered, had a TA shaker, and a very well done "subtle" flame paint job. The car had the perfect stance, and really was a standout for a largely ignored body style. Never seen another one as eye catching until yours. Way to take it to the next level - very well done!

Grand Am Dyno Session Video
I had a dyno day at Westech Performance to tune the GA and get some numbers on power. Car ran fantastic. The final numbers were 482 RWHP@6300 and 484 RWTQ @4600. I am very happy with the numbers. The torque curve is huge and flat. The technician said to figure a factor of 20% give or take for flywheel power. That equates to around 600 hp/tq. As far as the way it runs, it spins the tires in 3rd gear!!Put it in 6th gear and just climbs the hills on the freeway. Car is very easy to drive. I could have went for a bigger cam profile and got the hero HP numbers, but that would ruin the idea behind fitting catalytic converters on the car, and building huge torque to match the feeling I had with the Pontiac 455. The car was fast with the 455, but the LS7 pulls so hard from down low to 6500 it's amazing. I would like to take it to the track and see what it runs. I took the car to the scales right after the dyno session and weighed it. It weighs 3950. So I would like to see the car hit the 11's, but traction will be the deciding factor. Enjoy. https://www.youtube.com/watch?v=9RzyMP0RraY

Retro Picture of Me and The GA
My buddy took this picture when I was waiting to weigh the GA. He photo-shopped it to B&W, and I think it came out AWESOME!! I am going to turn this into a big poster size picture and hang it on my garage wall. Car weighs 3950.
