Whatcher budget???
Cam, header, new Weber Carb, head with OS valves and a 3 angle valve job. Should give you a very street-able 115-120 hp engine, stock is around 97hp. 82 was the last year for the twin row cam chain (bullet proof) and what is called the short block. In 83 Toyota went to the single row cam chain (booo) and the tall block. Check your engine before ordering parts.
