My street Challenger. Basically a slightly modified stocker. Small block, 4 speed, aluminum wheels, radiator, and intake, power steering, manual factory disc, headers, full exhaust. No cage or bar. 3580 w/o driver. Now as a race car yes you can lighten it up. But as a streeter it'll be 3700+ with driver easy. My previous race car made just over 700hp. It ran a best of 10.13@133@3475. No exhaust, loose converter, 4.10. A low 10 car needs at least a bar, exhaust for the street. At street weights that requires at least 700hp.
