Throttle body [ETC], Oil Pan, and Camshaft are the biggest differences and the lack of EGR on the Vettes. The cam differences are not enough to show a performance gain. The F-body cam has more lift but less overlap.

'98 LS1 is a '98 LS1. Some of the accessories are different vette to F-body (TB cable vs wire, exhaust system, and no EGR for the Vette), otherwise the engine is the same.

Everyone needs to get into the " New LS1 Owners - Newbie Tech" and read the stickies in there. All of this info has been gone over countless times.
