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.

Got Bored....Painted the Cowl Area
Until I get the frame back, I have to keep myself occupied on this project by doing some of the liitle things that need to be done, or the things that bug me. The cowl area was painted back when the car was painted in 2002. I didn't like the way it looked lately. The paint was a little dull. So I decided to redo the area with a little texture. I used Duplicolor Armour bedliner. I taped off the car, sanded the area down and shot it with the spray can bedliner. Three coats, followed two light coats of low gloss black. I think it looks a lot better?

Corvette Accessory Drive Parts Received
Today I received the Corvette accessory drive with A/C, Corvette water pump and GMPP Pontiac valve covers that I ordered from Superior Chevrolet. GM does a nice job with the instructions, and even has every bolt in the kit labeled with part numbers to make installation easy. I plan to get the mock up block back into the chassis so I can fit the A/C on the block to see if I need to notch the frame for the A/C pump. The only part of the accessory drive I will not be using is the belt tensioner. I decided to go with Katech belt tensioner instead. I will be taking the power steering pump to Lee Manufacturing next week to have them modify the internals to accept the hydroboost.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
