This car was marketed in 1975 and 1976 as the Cosworth Vega. This car was produced on a limited scale assembly line at GM's Tonawanda N.Y. assembly plant. The head made it necessary to upgrade the existing Vega block which found its way into all Vega's in 1976 and on and cured most of the original engine's problems. In the Cosworth application the block was destroked to 2.0 liters from the orginal 2.3 liters. Multiport electronic fuel injection and stainless steel tube headers were added to the engine. The stock F41 suspension was upgraded as were the brakes and rear axle. The 1976 Cosworth Vega came with a 5-speed transmission. GM made 3700 of these cars before they decided that they were not worth the trouble. I guess in 1976 a small high revving engine was still not recognized. I hope in 1984 they are.
