What is the best setup for a to get the most power I can out of it without blowing it up? A uses a 3. While the was among the best-performing engines of its day and was certainly durable, it was also small. While it is true that a larger cubic-inch small block will make more power given its much larger displacement, it is certainly possible to make decent power. But with 1. Using that same 1. Of course, there are ways to make more horsepower by revving this smaller engine higher and by using big-port heads, but that does not fit within our goal of a mild, affordable street engine.
