My girl!

Ever since I was in high school ('89-'93) I wanted to some day own a 1987 Buick Grand National. The combination of power, speed, class and just plain intimidation was mesmerizing. It took 15 years, but a few years back I finally got one. Of course, she needed a bit of work.... At first, it was just the ignition, then the wastegate, then the rear main seal, then the transmission..... You know the deal. Now, finally, she is nice and healthy and ready for me to get to work on the interior. Which means lots of PG goodies!
As far as the motor goes, she dyno'd 497 HP and 506 ft/lbs at the rear wheels, running about 25 psi of boost, on 93 octane pump gas. Not much left stock under the hood.
