Back in 1974 GM commissioned Cosworth to develop a four valve head
for the Chevy Vega. 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.
