5.7L V8 TBI OHV 16V

This particular Chevrolet V8 Engine produces 245 HP @ 4400 RPM and produces 345 of Torque @ 3200 RPM although I'm not sure Chevrolet produced a TBI L98 V8, are you sure its not a TPI instead? TBI's are carbureted engines, while TPI is a more modern fuel injection system used in most late 80's and early 90's cars and even used today. Anyways hope the info was helpful, thirdgen.org can provide you with more answers if you have a Firebird or Camaro 82' - 92' ;)
