The Vortec 5700 L31 (VIN code "R") is a 5.7L V8 truck engine. It is Chevrolet's last production first-generation small-block. The cylinder heads feature combustion chambers and intake ports very similar to those of the LT1 V8, but lacking the LT1's reverse-flow cooling and higher compression.
The engine block had 4.84-inch (123 mm) bore centers, two-bolt main bearing caps, a "side oiling" lubrication system (the main oil gallery located low on the driver's side of the crankcase), with full-flow oil filter, and interchangeable cylinder heads. Heads used on the high performance 409 and 427 engines had larger ports and valves than ...
Along with the increased bore spacing, the new 3.6 L DI V6 has larger bores than before, growing from 94 mm (3.701 in) to 95 mm (3.740 in) with the same 85.8 mm (3.378 in) stroke as the 3.0L LGW, for a displacement of 3.6 L (3,649 cc). Intake and exhaust valves are also increased in size along with other changes to the cylinder head. [21]

Vortec is a trademarked name for a line of gasoline engines for General Motors trucks. The name first appeared in an advertisement for the 1985 model year 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber , creating a better air / fuel atomization. [ 1 ]
From 1994 to 1997, it used sequential port fuel injection, and made 210 hp (157 kW) at 5200 rpm and 215 lb⋅ft (292 N⋅m) of torque at 4000 rpm. In 1996, the heads were redesigned for better flow, as well as now making the engine an interference design and adapting the engine for federally mandated OBD-II emissions. Output for the 1996–97 ...
