| | The Repair Library - 09.03 Pontiac Fiero (Site not responding. Last check: ) |
 | | Pontiac engineers were admirably daring in their use of new procedures and materials, so much so that development costs exceeded $700 million even though existing GM major components were employed. |
 | | As we said, the engine that motivated the original Fiero was Pontiac's Iron Duke, albeit an improved version with a swirl-port head that allowed the compression ratio to be raised from 8.2:1 to 9:1. |
 | | Five mains support the nodular iron crank, the cam is driven by gears, and pushrods operate the valves through stud-mounted rockers. |
