* 262 CI: Used in 1975, low hp, smog engine designed for reliability with high MPG. Only used with the Chevrolet Nova and Monza (with 4.3L badges when optioned with the Monza) - NOT to be confused with the 1985-2014 4.3L V6-90 which has the bore/stroke of the SBC 350. | * 262 CI: Used in 1975, low hp, smog engine designed for reliability with high MPG.

| − | * 265 CI: Chevrolet's first SBC. Far surpassed in performance by the 283 and 327 engines that came shortly after. Consider this one for restorations only (unless you like a challenge). | + | * 265 CI: Chevrolet's first SBC. Far surpassed in performance by the 283 and 327 engines that came shortly after.

An unrelated 265 appeared in 1994 as an LT1 derivative using the bore of the 305 and fitted with a 3 inch stroke crank and 5.94" rods. |

* 283 CI: Chevy's first engine to produce 1hp per CI. Provides hp in the higher RPM, good for [[Reducing vehicle weight|light cars]] and higher RPM in performance applications. | * 283 CI: Chevy's first engine to produce 1hp per CI.

* 301 CI: This is a 0.125" overbored SBC 283, it needs a block with thick cylinder walls (recommend sonic testing first) and is no longer recommended (or necessary) practice, instead the preferred method is to use a 350 block and a 283 crank with spacer bearings if you want to build one. Actual displacement is 301.6 cid. | * 301 CI: This is a 0.125" overbored SBC 283, it needs a block with thick cylinder walls (recommend sonic testing first) and is no longer recommended (or necessary) practice, instead the preferred method is to use a 350 block and a 283 crank with spacer bearings if you want to build one.
