Small block Chevys were designed to be high revving. Light weight and a short stroke\/large bore design let that first 265 cubic inch engine make good power up to about 5000-5500rpm, unheard of in 1955 when flathead Ford V8s ran out of steam at three grand or so.<\/p>\n

Today you can build a small block Chevy to make power well beyond 7000rpm with the right parts. One of the secrets to a high-RPM small block is reducing rotating assembly weight. A lightweight assembly can spin faster, so the engine can hit its powerband quicker. It also takes less horsepower to rotate, so you gain back some extra power.<\/p>\n

A lightweight rotating assembly also improves the car\u2019s acceleration and deceleration. That last point is a big plus in circle track racing as faster deceleration in the turns means you don\u2019t need to hammer on the brakes as hard.<\/p>\n

A good place to start your rotating assembly\u2019s diet is with a Scat Excalibur Lightweight Crankshaft. Forged from 4340 steel, an Excalibur crank weighs around 22kg depending on which one you choose. The cranks are precision-ground, heat-treated, and nitride-hardened for superior wear resistance.<\/p>\n
