- Mopar Performance A4 Aluminum Engine Blocks & Components
The Mopar A4 engine is a 4-cylinder aluminum block racing engine that is based on half of a small block Mopar. This engine uses one small block Mopar V8 cylinder head, valves, rocker arms, valve cover, and header. The drag racing versions of this block have the small block Mopar bell-housing and can be used with a transmission. The Midget versions of the block have the bell-housing machined away to save weight since these racing engines are not used with a transmission.
