Turbo Engine: Turbo Small Block Build

Did You Know?
The cam journals in GM blocks are bored with three different inside diameters so the bearings can be loaded on a stepped tool and installed all at once to speed assembly and reduce cost. Dart bores all the cam journals to the same size so they can line-hone them to a finished dimension. This makes a more precise diameter and ensures true alignment of the journals. It also means all the cam bearings are the same size.
