Chevrolet Small Block V6 Engine
The Chevrolet Small Block V6
The Chevrolet V6 has become a very important Jeep conversions engine, and is swapped into many Jeeps with great frequency now.
By 1978, Chevrolet had 23 years of building its famous Small Block V8 under its belt. The energy and fuel crunch of the era dictated a lighter, leaner motor than the V8 and GM took on the engineering and production of an important new engine.
Development
This new V6 would essentially be a V8 with two cylinders truncated, as Buick had successfully done with its V6 in the 1960's. The Chevy 90-degree V6 had the same rear block face & bolt pattern, as well as the same style of engine mounting bosses and accessory packages as its bigger brother. Because its crank was a shortened version of the V8 crank, this motor was an "odd-fire" design, firing its cylinders at uneven intervals. The motor was internally balanced and would feature the standard two valves per cylinder.
The Release and Evolution The motor first featured a displacement of 200 cubic inches and in 1980, this was increased to 229 c.i.d. It was largely found in Chevrolet cars during this era. In 1985, the V6 underwent its next upgrade to 262 c.i.d. - equivalent to 4.3L. It was converted into an even-fire motor. To do so, it was necessary to balance the motor externally and the flywheel was no longer interchangeable with the earlier V6's and most SBC V8's. In 1986 it received the one-piece rear main seal improvement that was also seen implemented in the V8's. The V6 was the first to be called the "Vortec" engine - nomenclature that GM would eventually pin on all of its advanced truck engines to this day.
