General Motors produced a plain pushrod (OHV) straight-4 engine for the J-bodycompact cars and S-series trucks. Displacement ranged from 1.8 L to 2.2 L with turbocharged 1.8 and 2.0 L versions offered as well. The final version was known as the 2200, and lived on as the Vortec 2200, though the earlier models were never even named. The line was eventually replaced by the Quad-4 and Ecotec Family II in the late 1990s. GM redirects here. ...

GM, for obvious reasons, likes to call this phenomenon "FWD Performance." Eventually, someone at GM realized the company had a new engine called the Ecotec that -- with a few "cheap" tricks -- had the potential to beguile a few folks currently exclusively in love with certain Japanese and European Import Performers.
GM Racing installed a package of components you'd certainly install if you were taking the trouble to open an engine to upgrade the connecting rods: Super-duty forged Crower X-beam rods -- plus 10:1 JE forged pistons with thicker top ring lands and Hastings moly ring packs.
The GM team solved this problem by reinforcing the two problem areas with twin studs that threaded through bored machined into the upper structure of the head and jammed against the outboard fire-ring areas of the head next to cylinders one and four.
The Vega engine, as it became known, was unusual for the time with an aluminum block and cast iron SOHC head.
It was available with a 1 or 2 barrel carburetor and was used in the Chevrolet Vega and similar Pontiac Astre, and the later Chevrolet Monza and its H-body siblings: the Oldsmobile Starfire, Buick Skyhawk, and Pontiac Sunbird.
The engine used a 3.501 in (89 mm) bore and 3.625 in (92.2 mm) stroke and 8:1 compression.
