Civi car built up with what was called an unrestorable police car. On ebay in 2011. Seller description
It is not an original squad car. It was built from a derelict squad that was way too rough to restore, all parts were transferred to this body. It is powered by a rebuilt 440, 10:1 pistons, MP 268/284 -458 Magnum cam, double roller timing chain, 452 heads with hardened valve seats, and an Edelbrock 6-Pack intake with Holley carbs. The 727 was rebuilt with a mild 2200 stall converter. The 8 3/4 rear has a 3.23 sure grip. It has extra heavy duty suspension and front and rear anti-sway bars and a 140 MPH certified speedometer.
