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 early70'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. The 350, 400, and 455 are interchangeable but today most Pontiac enthusiasts want the 455 with aluminum cylinder heads. With this combination we can make over 550hp with incredible torque for the dream machine muscle car.
