someone needed it.
The Vortec 5700 L31 is a V8 truck engine. Displacement is 5.7 L. It is the last production Generation I small-block from Chevrolet. The cylinder heads feature combustion chambers very similar to those of the LT1 V8, but without the reverse-flow cooling. As such, the L31 head is compatible with all older small-blocks, and is a very popular upgrade. It offers the performance of more expensive heads, at a much lower cost. It does, however, require a specific intake manifold (a Vortec head has four bolts attaching the intake manifold as opposed to the traditional six bolts per head). The L31 was replaced by the 5.3 L 5300 LM7. The 2002 model year was the final year for the L31 5.7 L small block V-8 whose origins date back to 1955. The Vortec 5700 is good for 255 horsepower (190 kW) and 330 ft·lbf (450 N·m) of torque bone stock. It is currently being produced as a crate engine for marine applications and automotive hobbyists as the "ramjet 350" with minor modifications.
