It'* very common to have an FE3 cutlass. It'* nothing more than a suspension code, and lots of W-bodies got it. It IS rare to have that little badge though. IIRC, an FE3 w-body could push somewhere around .83g in a 300ft skidpad (this is based of a '92 Z34 / '89 TGP). Something suprising about these cars is the amazingly low drag coefficient. The Cutlass had the lowest of any W-body at .297.
