You are bidding on a solid 1968 Firebird Convertible. This was originally a 350 car but a correct year 6.6L 400 cubic inch engine has been rebuilt and installed. I spared no expense on a STRONG 400 engine rebuild. I have included an extensive log of parts and costs associated with this car build which can be viewed in the images. I have all original receipts and manuals for these upgrades and more that will be included with the car as well as a number of miscellaneous parts such as replacement bulbs for the reverse lights.

I have built this for daily driving. For safety I added four wheel disc brakes and BRIGHT LED tail lights. For handling I added pro touring suspension and a larger sway bar. This car handles like a new vehicle and stops quickly. The 408ci 6.6 liter V8 sounds and performs great pushing between 400-450hp. It has a 3 speed automatic with a 12 bolt Eaton brand limited slip ‘Positraction’. The gearing allows for cruising at highway speed. I’ve added some additional interior images to the listing.
Please send me any questions and if they pertain to all I will post those as they come in.
