This is an excellent collectors car with everything working and is in extremely good shape. I thought I would never sale this car but rite now my daughters education is more important!! I am the 3rd owner of this car it has been garage kept. I have recently rebuilt the motor and transmission. I have also completely rebuilt the front end including the upper and lower A frame bushings. The transmission has been bullet proofed it has all new red eagle clutches,new metal,new shift kit,new billet servo,new stator,new hardened billet tail and input shaft,new 12 vane pump, new hardened billet drum and a new 2800 series stall converter. You will never have to worry about this transmission again or worry about it being able to handle the power the motor puts out!! The motor also has been completely rebuilt it has been bored 40 over and has new forged pistons, new 4340 crankshaft, new 218 comp cam, new 42lb injectors,heads have had a 3 angle valve job and have been ported and polished,new double roller timing chain and gear,new heavy duty oil pump,new heavy duty high volume fuel pump,new external fuel pressure regulator and gauge,new 4 core aluminum radiator with temp and pressure gauge,new down pipes and new intercooler, new ijnition coil,new ijnition module,alky injection kit,new TE63 turbo and is rated at 600+ HP new 3in exhaust pipe some of the parts and most of the work was done at Jack Cottons performance shop. I have upgraded the front ant rear brakes and installed a hydro boost for better stopping power!! This motor is producing between 540 and 560 HP I'm not a drag racer but I did take the car out to the track once just t see what it would do. I was running 15lbs of boost 93 octane pump gas and denatured alcohol from Lowes hardware store and the car ran a 12.2 in the quarter the car is setup to run 25lbs of boost so I'm sure it will run in the 11s with no problem with the proper fuel mixture like 114 octane race fuel and methinol with a little more boost. I have also installed coil over air bags in the rear. This car is awesome to drive and evertythimg works great including power windows,power door locks power seats A/C works just needs freon I just haven't taken it to the shop and had them pull a vacuum on it and recharge it since I've rebuilt the motor. The radio works it is new CD player/radio I also have the original GN rims and tires and a set of TA rims and tires for the car both sets are in great shape and like the motor and transmission have less than 200 miles on them. I would not hesitate to drive this car across the country. I also have a set of Drag radials on new rims. If you have anymore question you can call or text me at 903-503-4114
