I will try and get video soon. So far I have it just set to 12lbs for a break in period. Probably one more week of daily driving and it should be ready to give a shot at the track and see how many lbs I can run with 93 octane.

Buick power! I love it. I'm curious to see how your car runs with the 700-R4. Why didn't you use a 200-4R? That car would be a bada$$ sleeper with the stock hood and crappy stock wheels.

Eric, turbo motor is looking good. I'll give you one complaint though; I'm getting sick and tired of seeing the exact same exterior pictures for the last 5 years! lol Snap some pictures more pictures at least for a refresh. Then you can use those until 2010.

Sitting in a shop?

Then that was your car in the photo!
Pontiac Enthusiast May/June 2006, page 61 dead center, sitting in the shop.
The story is about the shop doing work on Firebirds.

"This slick third-gen Firebird is indergoing a turbo-motor transplant, using the same Grand National engine that fitted to the '89 Turbo Trans Am pace car replicars. Pretty cool, huh? The white fourth-gen car next to it runs high 8s."
Sorry, but the new issue is already out, so either check the swap meets, or order a back issue!
Just a heads up!
Enjoy,
George
