C3 Corvette Performance Upgrades

Customizing the exterior of a C3 Corvette can be fun but the real jolt comes from upgrades to the Vette's inner workings. Enhancements to get more power from the Vette's world class engines to the point where the tires meet the asphalt help the car not only look good standing still but also run like a starving cheetah after an antelope, and that kind of performance is what the Corvette experience is all about. Car show patrons know when a car looks good, but only the driver knows how well an individual Corvette handles the road. That makes this sort of personal modification one of the most satisfying an owner can undertake.

One advantage of many performance mods is extended working life. Starters, for instance, are very vulnerable to the heat given off by the manifold and the exhaust system. A heat shield can protect the starter's armature, preventing the hard starts caused by degradation. Heavy duty timing chains are more durable than OEM units, and may offer lower friction for better operation. Specially engineered engine pulley systems also reduce the amount of friction in the system, eliminating some of the drag and increasing the power that can go to the road rather than the accessories.

Parts like these can tease more power out of any Vette, but some of them are not street legal in every state. For help choosing useful and legal modifications for your custom Corvette, contact the experts at Corvette Mods. Tell them where you live and how you plan to use the car, and they will offer real world advice about modifications to help you get the most from it.
