As a general rule, automotive engines can have a much higher HP rating, because it's only required to produce this peak output for very short bursts and amounts to a small percentage of the total time the engine operates. This isn't true with marine applications, where the engine must develop the peak output most of it's life. This is why the 350 CID Crusader engine produces 230 HP, but requires the "pink" (developed for racing) GM rods installed. The same engine built with the same parts would have a warranty from GM in one of their cars with over 400 HP and one could be expected to get 200,000 reasonably trouble free miles from it.

Engine Assemblies:Engine assemblies refer to sets of engine components required to make up a complete automotive engine. Engine assemblies are needed to perform partial replacements, engine swaps and direct engine replacements. A typical packaged engine assembly may include a number of engine parts such as lower blocks, connecting rods, crankshafts, main bearings, rings, rod bearings, pistons, etc.
The chief characteristic of an automotive engine (compared to a or a ) is a high . This is achieved by using a high rotational speed. However, automotive engines are sometimes modified for marine use, forming a .
Automotive engineers generally work in offices on computers, but they also travel to manufacturing plants to conduct experiments or collect data.
