'84 Buick Grand National


Well-Known Member
For sale is a 1984 Buick Grand National. I have owned this car for the past 6 years, since May 2009. I purchased this car out of Phoenix, AZ with 85k miles. The car currently has 97k miles, that works out to 2k miles per year since my ownership.

This car has been a California/Arizona car so there is NO RUST on this car. I had this car 22 months garaged in North Carolina while I was living there. I have had this car garaged in Texas since I moved here earlier this year.

The reason for the sale is to move on from these cars as I just purchased another project.

Car is currently running 23lbs of Boost on pump E85 Fuel. You can run 93 octane by swapping the chips in the computer but will need to lower boost to 17-18lbs.

Paint is original Laquer paint that has chips and scratches but still polishes up nice.
Front speaker tray is cracked. Small tears at the top of the rear seats. Steering wheel has wear at 12 O'clock. All cosmetic.

The Engine/Transmission was built by Nick Micale from www.ArizonaGN.Com on March 2013. I have put 2,800 miles on the car since the build. Below is the list of the build and what the car currently has. Engine was built to run consecutive mid/high 11s in the 1/4 mile.

Engine oil has been replaced with Valvoline VR1 Racing Oil + ZDDP Additive every 1,000 miles or 6 months. The Transmission fluid was changed with Dexron VI 1,800 miles ago after I swapped out the torque converter for a higher stall. Rear Differential Fluid was changed 1,600 miles ago with 75w-90 Gear Oil and a bottle of GM Limited Slip bottle. Power Steering fluid changed 200 miles ago with Fresh Power steering fluid. Brake Fluid was changed 200 miles ago with DOT 3 fluid. For Coolant I am running Distilled Water with RMI-25 and 20% anti-freeze.

Took the car out to let it run for a bit and I also recorded it with the Power Logger. Attached is the log of it running so you can see engine values. I also recorded a video with my phone, please select the 1080P option for better quality. Thank you.
