Have you ever thought about how the correct rear axle ratio affects your Corvette’s performance? First, learn what ratio you have hidden away in the differential housing. Early Corvettes (1960-1970) may have many different ratios; later Corvettes had fewer choices, in an effort to boost fuel mileage, and by the mid-80s performance gear ratio options […]

67-69 Tri-Power Carburetor Tuning/Troubleshooting
What is your first impression upon seeing all these carburetors in a row? Sheer terror or wondering why they would do something that crazy? A few of us actually must have them. When the carburetors are set up properly, the feeling of an additional four barrels opening is exhilarating. The acceleration rate is similar in […]
Steering Wheel Installation
One of the first things you notice when you look at the interior of any car is the steering wheel. Years of handling tends to make them ratty and, frankly, disgusting. A fresh steering wheel almost feels like fitting a good pair of new shoes.
C5/C6/C7 Engine Cleaning
Whether you are prepping your Corvette to roll across the auction block or display at a show, a spotless engine shows how important and well-maintained your Corvette is. Filthy engines are more apt to retain heat and make it difficult to detect small leaks. Dirt and dust cause pulleys and belts to squeak from undue […]
Sealing a Shark: 1977-1982 Weatherstrip
Using aftermarket weatherstrip pieces in the past, we had to choose either adjusting the windows to seal, or adjusting the windows to roll up and down without the door open. There was no way to do both. ’77 and earlier models used a different style rear vertical weatherstrip that wasn’t solid so it made window […]
C3 Radiator Core Support Installation
The radiator core support has two functions: radiator placement and front end support. Weakened core supports allow the nose of your Corvette to droop, increasing the gap between the upper part of front fender and the door. When that occurs, stress is placed on the inner fenders. Before the core support project begins, a thorough […]
1963-1982 Corvette Rear Bearing and U-Joint Overhaul
Mechanical projects can be fickle. You start simple and before long it is an all-out assault. Our initial intent was to simply replace the leaking brake calipers and possibly the rotors on our 1969 427 convertible but we found ourselves heavy into the wheel bearing grease.
Addendum: 1955-1966 Corvette Fuel Pump Rebuild
In a previous article, we covered how to restore your fuel pump. Those were the days! Disassemble the fuel pump, replace the check valves and diaphragm, and you were back in business. I have always felt fortunate that when I started out in this business, engines had carburetors and emission systems were in their infancy. […]
C5 Battery Leak
If you own a squeaky clean C5, you’re still likely concerned about an acidic force that could be slowly destroying your prized possession: Battery electrolytic acid leakage.
C4 BOSE WOES: Repairing & Replacing 84-96 Bose Speakers & Amps
If you own a C4 equipped with Bose sound system, you will eventually need Bose amplifier repair or replacement. Every Bose sound system equipped C4 uses one amplifier per speaker. This is the weak link. Amplifier capacitors are filled with electrolytic fluid, which ultimately leaks out onto the circuit board, causing failure. If the […]
