Are all Chevy small blocks the same?
Chevy small blocks are not all the same, as there have been different generations and variations of the engine over the years. Here are some key points to consider:
– The first and second-generation Chevy small-block engines had some unique features, such as different water pumps, intake manifolds, and damper/pulley systems.
– Despite these differences, GM kept the engine mounts and bellhousing bolt-pattern the same, allowing for easy transplantation of the new engine into older chassis.
– The Generation II small-block had aluminum heads, reverse flow cooling, and advanced electronic controls, but it was still based on the classic small-block design.
– The Generation III engines, also known as LS-series engines, are a significant advancement and have become widely available and affordable. They have been embraced by the aftermarket in a similar way to the original small-block Chevy V-8.
– There are also differences between specific small-block engines, such as the 400 and 350. The 400 small block is more about horsepower, while the 350 can provide decent performance and fuel economy.
