Applications Assembled overhead valve engine with heads and complete valve train but without manifolds, rocker covers, timing chain cover or oil pan The V8 with a crossplane crankshaft (see below) is a very common configuration for large automobile engines. V8 engines are rarely less than 3.0L (183cuin) in displacement and in automobile use have gone up to and beyond 8.2L (500cuin) in production vehicles. Industrial and marine V8 engines can be much larger.

Assembled and installed with all components as seen in a rear-wheel drive vehicle V8s are generally only standard on more powerful muscle cars, pony cars, sports cars, luxury cars, pickup trucks, and SUVs. However they are often optional on vehicles which have a V6 or straight-6 as standard engine. In many cases, V6 engines were derived from V8 designs by removing two cylinders without changing the V-angle so they can be built on the same assembly lines as the V8s and installed in the same engine compartments with few modifications. Some of these employed offset crankpins driving connecting rod pairs, enabling a more regular firing sequence.
