The 351 crate engine is a powerful engine with excellent fuel economy.

The 351 crate engine is one of the high performance engines in the motor industry. It is relatively costly in price but also one of the most gas efficient engines in the market today. With a horsepower range of 300 to 350, it is a high performer costing several thousand bucks. This model of engine has also been here for sometime and shares a lot of qualities with the 350 crate engine. Being a high performer, it can be used on trucks and boats that need a lot of horsepower to carry out their functions.

This engine can be modified and other parts put into it for it to work better and faster. The rpm levels of the 351 crate engine are within the limits of 5000 to 5500. When the 351 crate engine is equipped with a 600cfm Holley, it can consume fuel even more economically and save the user a lot in terms of gas usage. The user is able to cover many miles on a tank of gas. It can cover many miles without the need for repair. These engines are bought with a warranty; and the more the warranty the better the quality of the engine you are buying. The horsepower it possesses enables the engine to achieve high speeds in a short time and use less gas in the process.

This engine responds well to changes in the engine to increase performance. It is one of the engines which can be head ported to increase their performances and this will not affect the performance negatively. The process is done by enlarging the head ports to increase the intake of air and fuel for combustion process. The more the combustion of the fuel, the better the performance of the engine and this means a subsequent increase in the head port of the engine. The horsepower can therefore be manipulated to increase the performance of the 351 crate engine. The increase in the inflow of air raises the power of the engine and increases the miles per gallon of gas. You can increase the fuel economy of your 351 crate engine by head porting. This essentially means that the air in the engine is increased by head porting. The fuel burns more efficiently as the speed of the engine reduces. The cylinder head casting is a factor that comes into play when head porting as this can increase the efficiency of the burning of the fuels as well
