1986 Buick Regal Grand National

This 1986 Buick Grand National comes heavily modified with no expense spared. The fully built 3.8L engine has been bored .030" over with forged internals, CompCams performance camshaft and lifters, Precision dual ball-bearing turbo, Alcohol Injection, HKS BOV, adjustable fuel pressure regulator, manual boost controller, external breather tank, 150 amp alternator, 4" deep intercooler, large billet throttle body and intake plenum, BigStuff3 fully customizable engine computer, Walbro high flow fuel pump, large Bosch fuel injectors, custom intake and exhaust piping and so much more. Here is a link to the engine running and revvinghttps://www.youtube.com/watch?v=LDYnN43HYXA. The engine and transmission have about 1,000 miles on them.
The transmission has been built with custom made components and is rated for 800 hp. The driveshaft is also rated for 800 hp. The car is currently putting out around 550 hp with a street tune and modest boost with the alcohol turned off.
Aside from the modifications, this car is rare on it own having options very few other Grand Nationals have. This car has T-Tops (2 sets), factory digital gauges, power windows, cruise control, and A/C (currently deleted, see below for more information). I have original paperwork and documentation. The radio has been rebuilt with modern internal components and added head phone jack to connect phone music. The brakes have been upgraded to vacuum powered instead of the stock powermaster unit. New shocks and other suspension parts are installed as well.
Also being transferred with the car are all of the original parts that were taken off the car as well as lots of new OEM parts still in boxes. There are more parts than whats pictured (limited by ebay). Some of which that's not pictured is an extra engine block and drag radials with rims. The A/C and Heat were disconnected to make room for the performance modifications and can be reinstalled with some fabrication work.
