Buick Grand National 1987 Description

1987 Buick Grand National Stage 2 Twin TurboI am selling my car. It’s time to move to some other projects I have been wanting to get to. This a rare opportunity to purchase a Stage 2 car originally designed and built by Kenny Duttweiller and currently rebuilt and tuned by Billy Anderson. The drivetrain from front to back is fresh. The engine has less than 1000 miles of a complete rebuild. The transmission and rear end have less than 300 miles. I took it to the track once. I drove 300 miles round trip. Averaged 14 miles per gallon. It ran 9.87 at 136 mph on straight 93 pump gas and 16 lbs of boost. That’s with a 5 lb launch and 1.40 60ft time.

This was a race car! I have refreshed the entire drive line and its running awesome. I was slowly trying to make it a more civilized street car. I drive it a lot though. It is different from most gn’s as it has manual brakes, steerin, no a/c. The car isn’t perfect. The paint is decent, but was sprayed without removing trim, has some runs, and could use a wet sand. The option code sticker is long gone with the original trunklid. The interior could use some love to be show quality, but there aren’t any rips or tears. The headliner is good.
This car does have a reassigned title due to a theft years before I bought it. I bought it with this and had no issues with title transfer. I also have a lean on it, so It would take several weeks to obtain the title from the bank. I have no issue with the buyer taking possession of the car during that time.I may have still missed some things and can provide any pictures to serious potential buyersThis car is crazy fast and a real head turner! It would cost over $60,000 to reproduce this car.
