| − | The 305 was introduced for 1976, to have a Chevrolet engine between the 250 and the 350. The small bore diameter of 3.736" limits breathing, which limits naturally-aspirated power, so this engine is much-maligned and shunned as a performance build. The primary appeal may branch from any combination of 3 common sources. The "underdog" appeal, already having one, and the success of the Ford 302 rival. | + | The 305 was introduced for 1976, to have a Chevrolet engine between the 250 and the 350.

The 305 is plentiful, and easy to get for cheap. The build is about as cheap as the 350, but the power-per-dollar is always less. In practice, there seems little real advantage in gas mileage over the 350, but you may get less costly insurance rates. | The 305 is plentiful, and easy to get for cheap.

Unless you already have a pre-'87 block, the '87-up is preferred, because of the cast-in provisions for the factory roller ( hydraulic ) lifters and the thrust plate for the cam. | Unless you already have a pre-'87 block, the '87-up is preferred, because of the cast-in provisions for the factory roller ( hydraulic ) lifters and the thrust plate for the cam. | ||
