What cars came with a 350 engine and 4 bolt main together?

Many Chevrolet small-block 350 cubic inch (5.7L) engines were offered with four-bolt mains, but it wasn't a standard across all applications. The presence of four-bolt mains was generally associated with higher-performance versions of the 350. Pinpointing *every* car model that ever had this combination is difficult due to variations in engine options from year to year and different trim levels.

However, you're more likely to find four-bolt main 350s in these types of vehicles and situations:

* High-performance models: Muscle cars, sporty coupes, and trucks with performance packages were more likely to have the stronger four-bolt main block. Think Camaro, Chevelle, Nova, Monte Carlo, Corvette (some years), and various trucks with performance options.

* Later model years (with caveats): While earlier models *could* have them, the prevalence of four-bolt mains increased over time as manufacturing techniques improved and it became more cost-effective. However, even in later years, not all 350s in all models had them.

* Specific engine codes: Chevrolet used engine codes that often indicated the internal specifications. Researching these codes for a specific year and model is the best way to know for certain if a car had a four-bolt main 350.

In short: There isn't a simple list of car *models*. You need to specify the year and often the specific trim level or option package to determine if a particular car came with a 350 small-block engine featuring four-bolt mains. Using resources like engine code databases and car specific forums will be your best bet for this level of detail.
