Editing Buick V6 engine (section)

====198====<!-- This section is linked from [[V6 engine]] -->
The [[Buick]] Division, concerned about high manufacturing costs of their innovative aluminum 215 V8, sought to develop a cheaper, cast-iron engine based on the same tooling. It was given the RPO code '''JL'''. They settled on an unusual 90° [[V6]] layout that was essentially the architecture of the '215' less two cylinders. In initial form, it had a bore and stroke of {{cvt|3.625x3.1875|in|mm}}, for an overall displacement of {{cvt|3234.5|cc|CID L cc|1|adj=ri0|order=out}}. It weighed about {{cvt|35|lb|kg}} more than the aluminum engine, but was far cheaper to produce. Dubbed the '''Fireball''' V6, it became the standard engine in the 1962 [[Buick Special]]. In their test that year, ''[[Road & Track]]'' was impressed with Buick's "practical" new V6, saying it "sounds and performs exactly like the aluminum V8 in most respects."
