The largest of the small blocks, the 400 debuted in 1970 and was produced for over 10 years. Featuring siamesed cylinders for added strength, with 4.125" bore and 3.75" stroke, the small block 400 was a torque monster. Speedway Motors carries a huge selection of high performance small block Chevy engine parts to help make your 400 motor really come to life.
