As the muscle car era was fading and fuel economy become increasingly important, Chevrolet introduced the small block 305. It featured a 3.75" bore and a 3.48" stroke. Through most of the mid '70's and early '80's the 305 was used on a widespread basis. If you're ready to make your 305 really roar, Speedway Motors has the high performance parts you need and the tech help to help get you through any installation.
