The information below is divided into the following sections: package contents, component information,
CT350 circle track engine specifications, additional parts that you may need to purchase, torque
specifications, and a service parts list.
The CT350 circle track engine is manufactured on current production tooling; consequently you may
encounter dissimilarities between the CT350 circle track engine assembly and previous versions of the
small block V8. In general, items such as motor mounts, accessory drives, exhaust manifolds, etc.
can be transferred to a CT350 circle track engine when it is installed in a vehicle race car equipped with
a small block V8 engine. However, as noted in the following sections, there may be minor differences
between a CT350 circle track engine and an older small block V8 engine. These differences may require
modifications or additional components not included with the CT350 circle track engine.
It is not the intent of these specifications to replace the comprehensive and detailed service practices
explained in the GM service manuals.
Observe all safety precautions and warnings in the service manuals when installing a CT350 engine in
any vehicle. Wear eye protection and appropriate protective clothing. When working under or around
the vehicle support it securely with jackstands. Use only the proper tools. Exercise extreme caution
when working with flammable, corrosive, and hazardous liquids and materials. Some procedures
require special equipment and skills. If you do not have the appropriate training, expertise, and tools
to perform any part of this conversion safely, this work should be done by a professional.
