We purchased this car two and a half years ago with 114k miles from the second owner (who purchased the car with 4k miles). It has had a few other engine combinations and served us well as somewhat of a test-bed for our performance shop. This car has just about everything you need to go the track or have lots of fun on the street. The motor was built for nitrous, however it has never been sprayed nor has any N2O kit has ever been installed on this vehicle.

On a conservative tune, through the steel driveline and 12-bolt, it produces 470 RWHP/430 RWTQ SAE on a Dynojet. With some more static compression, this heads and cam combination is capable of 500+.

The drivability is excellent for a combination of this caliber with no surging, hesitating, or stalling. The A/C system is intact and blows cold.

As much as we would like to keep this car and start going to the track with it, personal priorities have changed and we just don�t have any time to enjoy it.

The winning bidder purchases the vehicle as pictured, with the Bogart RR10 wheels. The two other sets of wheels (listed above) can be included for an additional price or either set can replace the Bogarts for a discounted price.
