Plus torque steer inherent with front-wheel-drive cars of the day would be unbearable for the average driver, if 300 horsepower were delivered to the front wheels. Rumors around this engine suggest it actually produced 300 horsepower when first designed but there was no transmission available at the time to reliably handle the power. In 1991 these were very impressive numbers. The engine produced an astounding 210 horsepower and 215 foot-pounds of torque.

This engine made 205 horsepower and 225 foot-pounds of torque. In 1989 Chevrolet teamed up with McLaren to produce a turbocharged engine of the yet to be introduced 3.1L. Chevrolet would soon push this engine to its real potential. The crank case was still cast iron and received little change. Generation three engines got a redesigned cylinder heads and intake with improved air flow. Generation three engines were introduced in 1993. The second and third generation engines were only used in front-wheel-drive vehicles. First generation engines V6/60-degrees are produced for front-wheel-drive and rear-wheel-drive vehicles exclusively.

First generation V6/60-degrees have cast iron cylinder heads with inline valves second generation engines have aluminum cylinder heads with splayed valves. Chevrolet's 60-degree V6 has been produced in three distinct versions. This V6 is not like any other Chevrolet V6 which have all been derived form their V8 cousins. It was designed with a 60 degree separation angle to give perfect balance and a crank throw angle of 120 degrees. This engine has received changes almost every year of its life and is now one of GM's most widespread engines.Д¬hevrolets engine started its life as a true V6 from the ground up. A Chevy V6/60-degree engine is the perfect power-plant for a high-tech street rod or an ultra light autocross machine. It is a proven winner in sports car racing, and it has a promising future on America's oval tracks in the Midget classes. This innovative engine has beaten both the competition and the elements in off-road racing. Launching in 1980 the Chevrolet 60-Degree V6 is a compact powerhouse.
