The 262 was installed in the Chevy Monza, Nova, and Pontiac Ventura. The 1975вЂ“1976 262 was a 4.3В L small block with iron block and heads. Horsepower levels ranged anywhere from 215hp to 250hp, depending on year and application.ДЄn engine configuration with a very short lifespan, offered in just two model years. The aluminum versions were limited to the Corvette, although an iron casting was standard on the IROC-Z and Z/28 Camaro, Trans Am, and Corvette starting in 1985. To improve the performance of the Corvette and F-body cars, the L98 cylinder heads (developed through the motorsports program) were offered on the 350 small block. There are eight other 350 variations (L65, LM1, ZQ3, L81, LT-9, L83, L05 and е…ѓ1), but most have little interest to enthusiasts. The high point of this powerhouse was the 360 hp LT-1, the low point following shortly after during the mid-вЂ70s to the early вЂ80s, when the Corvette made due with the under-powered L-82, producing around 200 hp, depending on year. It was introduced as the 300 hp L-48 in the вЂ™67 Camaro, and over the years found its way into all of the other Chevy models.

The 350 holds the record as the longest produced small-block Chevrolet engine made, and itвЂ™s powered just about everything imaginable. Despite using stock rods and crankshafts (carefully inspected and shot-peened) the components were used to 7000 rpm during Trans-Am races, producing about 440 hp. Only being available for three model years, and offered exclusively as the standard engine in the Z/28 Camaro of вЂ™67-вЂ™69, the high-revving 302 combined components from the 283 and the 327, respectively, having been designed to meet the 5.0 L capacity limit of the SCCA Trans-Am Championship. It was used widely in the Chevy II / Nova and Chevelle models. Produced from 1968 to 1972 it utilized the same 3.875вЂі bore as the very first Chevy small block, but with a wider journals to accept the 327 crankshaft. The 307 was the last of the Generation I small blocks that link back to the original motors of the mid-1950s. At 1.146 hp-per-cubic inch it held the record for power to displacement for a small block for almost 40 years until the 2001 Gen III LS6. The most impressive 327s were the 365 hp L-76, and the amazing 375hp L-84 which was equipped with mechanical fuel injection. Introduced in вЂ™62 and available on all models from the Chevy II to the Corvette, the high-revving 327 came in a variety of specifications throughout its short-lived lifespan ranging in horsepower numbers of 210 to 375, respectively. The fuel injected version of the 283 was also an available option on the passenger car line as well as the Corvette, making any vehicle equipped with this advanced fuel delivery system a collectorвЂ™s item today. Also in 1957, the 283 was the first Chevrolet engine which offered factory fuel injection, helping the motor develop the magic 1 hp-per-cubic inch output.ДЇive variations of the 283 were made available in 1957 alone, ranging from 185hp to 283hp thanks to the option of a single, dual carburetor or the Rochester mechanical fuel injection system, which produced the magic 1 hp per cubic inch. A thicker-cast block needed to be produced (which also became the first engine block that hot rodders began using). It was an available option for all Chevrolet passenger cars, pickups, and was key in raising the status of the Corvette.ДЇor 1957 Chevrolet originally had plans simply to over-bore the 283 engine to 265 CID, but found that the previously-cast blockвЂ™s walls were thin. Despite a rather significant shortcoming (no oil filter) The engine provided so popular it was carried over with changes into 1956. The 265 small block was released in the all-new for вЂ™55 Chevrolet models with either 162 hp or 180 hp, depending upon carburetor and camshaft. Lead engineer Ed Cole and Corvette guru Zora Arkus-Duntov developed the light, simple motor in just 15 weeks time.
