The 1998 refresh reshaped the nose (new front sheet metal, composite headlamps) but the headline was the powertrain: the all-aluminum Gen III LS1, fresh from the C5 Corvette, replaced the cast-iron LT1. Officially 305 hp and widely regarded as underrated, it's the reason late fourth-gen cars remain popular tuner platforms.
The powertrain and identification notes below preserve configuration and model-year boundaries rather than treating every 1998 Camaro alike. Ratings use the measurement convention of their period, and visual cues are only a starting point: the VIN, factory labels, drivetrain identifiers, and surviving documentation should agree.
