Big Inches of Small
Block Chevy Power
The "World Class" engine line represents ideal powerplants for many muscle cars and street machines, as well as for street rodders who appreciate performance combined with easy maintenance. Hydraulic cams are used so you won't be popping off the valve covers often to adjust valve lash. Each engine is properly broken in and dyno tested to confirm that it meets or exceeds published specs (dyno sheet included with engine). Uses pump gas. 2 year/24,000 mile warranty.
