The Pontiac V-8 was the power plant for a whole generation of muscle cars, including the legendary GTO and Firebird Trans Am from the late 60's to early 70's. The renewed popularity of muscle cars has restored the interest of hobbyist rebuilding and modifying these engines. Although these blocks are few in numbers, they can be found and can also be totally custom rebuilt to any specific horsepower.
