#4.3L (262 cid) is 3/4 of the SBC 350 and as such, shares some of the parts and dimensions with the 350. Made 1985-2014. The 1992 model year saw the first use of a balance shaft; all 1995-present 4.3L V6 engines are equipped with a balance shaft. The 4.3L V6 got a revised cylinder head in 1996 with specs much like the SBC V8 [[Vortec L31 cylinder head]]. Passenger car usage was limited to B and G-bodies; after 1990 (with the exception of some 1991-'92 fleet Caprice) the 4.3L V6 was used exclusively in truck/van/SUV and marine/industrial use. | #4.3L (262 cid) is 3/4 of the SBC 350 and as such, shares some of the parts and dimensions with the 350.
