Could have had, I think, a 383 or 440 Wedge V8. Not sure if the 426 Hemi was still available. This garage often has interesting cars in its parking lot.
Very handsome car, a real performance car. The last of this second generation of Chargers, the top engine option was the 440 cu. in. Six Pack with three two-barrel carburetors and 390 hp, and was reputedly faster than the fabled 426 cu. in. Hemi.
