A redesigned cylinder head and manifold for improved air flow. Variable exhaust valve timing (the LW2 engine only had variable intake valve timing) Specially-developed fuel injectors. New pistons with pentroof-style centre-domes and valve eyelets for a higher compression ratio of 12.2:1 (compared to 10.2:1 for the dual fuel engine).
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.

The 304.6-cubic-inch (5.0 L) 305 had a 4.25 in × 3.58 in (108 mm × 91 mm) bore and stroke.

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 ]
