Performer RPM E-Tec 9.5:1 Engine
435 Horsepower & 435 ft/lbs. of Torque
Started with a "ZZ" GM Goodwrench 350 short block then added 64cc
E-Tec 170 cylinder heads that have Vortec-shaped intake ports. This
combination, along with the camshaft that works with the 9.5:1
compression ratio, manifold and carburetor, produces smooth power
from 1500 to 6500 rpm. They have the option of coming in a natural (as-cast) or polished finish. The polished option includes intake manifold, cylinder heads, and water pump (where applicable). The crate they are delivered in can be kept and reused or returned to Edelbrock for money back.

Now Edelbrock Crate Engines come with a 2 year unlimited mileage warranty.
