[Guide] 1963-1967 C2 Corvette Bolt-On Mods to Make More Power

The time spanning from 1963 to 1967, was an era of much change and growth for the Corvette. These second-generation Corvettes exhibited ever-continual growth in the performance department, while also showcasing a level of styling that had previously been inconceivable in the automotive world.

The C2 generation of Corvettes was also the first of the line to carry the Stingray monicker. When the 1963 Corvette hit showroom floors across America, prospective buyers and window shoppers alike gazed in amazement at the iconic American sports car’s new aggressive look. A vented hood design and deep body lines made the C2 Corvette a hot commodity among automotive die-hards from coast to coast.

The C2 generation of Corvettes also touted notable performance and drivability upgrades as the 1960’s progressed. GM sought to shake disparaging remarks pertaining to views toward ride quality and choice of power plant in the previous Gen 1 Corvettes.

With all-new independent rear suspension and big-block engine offerings that rose to prominence during the second-generation production run, the C2 Corvette went a long way to crushing the doubts of nay-sayers.

Although this timeless classic rolled off the assembly line as a true feat of GM engineering, countless C2 owners strive to maximize their Corvette’s potential by performing various mods.

The following is a basic guide to modding your C2 Corvette.

Suspension Upgrades

In 1963, the Corvette began its long-lived use of the transverse leaf spring. This benefited the Corvette’s ride quality immensely over the C1’s primitive solid axle design. Although C2 Corvettes came standard with a notably improved independent rear suspension, there has still been much technological advancement in this realm since the 1960s.

Suspension upgrades offer a number of advantages for any C2 Corvette owner due to their ability to increase stability, improve cornering, and enhance ride quality. While advancements of this nature come with a level of initial investment, the reward is often well worth the effort.

Eckler’s Rear Coil Over Kit

Do you have the urge to upgrade your C2’s suspension to its maximum potential? If so, then the Eckler’s Rear Coil Over Kit might just be what you are looking for.

This kit completely replaces your Vette’s stock transverse rear leaf spring components in favor of lightweight and fully adjustable Shark Bite Coil Over shocks. This becomes a noteworthy upgrade, due in part to the ability to fully adjust ride height stiffness while on the vehicle. This allows for a complete level of ride customization that the transverse leaf spring units that came standard on C2s could only dream of.

Perhaps one of the most valued characteristics of this kit is that it is completely bolt-on and no permanent modifications to the vehicle are necessary. This keeps your Corvette’s value intact, while also providing ultra-modern suspension that can be set based upon driver preference.

At a price of $1749.99, this kit not only includes all needed components and hardware but also thorough and concise instructions that make installation a breeze as well.

This kit is a direct replacement for the dated stock components from the days of the C2’s release and has everything you need to increase ride comfort and handling capabilities.

Electronic Ignition Conversions

Another area of automotive technology that has seen great strides since the 1960s is in the electrical department, more specifically with the advent of electronic ignition. Before GM’s introduction of the newer Delco HEI system, ignition was derived from the basic points and condenser variety. While the points and condenser systems of old certainly worked, they were the source of yet another additional maintenance task, and any voltage irregularities could spell trouble.

By converting your Corvette over to the use of an electronic ignition system, you gain an install-it and forget-it piece of mind that was simply not true in reference to the former points and condenser units. Electronic ignition systems run off of a magnetic field that is governed by the constant rotation of the distributor cam lobes while an engine is running. This eliminates the need for replacement of corroded or burnt points.

Pertronix Ignitor Conversion Kit

Are you completely dismayed at the thought of performing this year’s ignition system maintenance? If so, install this Pertronix Ignitor Electronic Ignition Conversion Kit, and toss your old points and condenser in the trash. What makes this particular mod so appealing is that you can maximize reliability, minimize future downtime for maintenance, and retain your Corvette’s stock under-the-hood look, all with a quick installation.

This Pertronix unit shines in its ability to retain the distributor’s outward stock appearance. The unit itself is mounted under the distributor cap, and the wiring that runs from the unit is discrete and not easily noticeable. This kit comes complete with everything needed for installation, including detailed instructions.

At a $90.99 price tag, this is a mod that is affordable to the masses.

 Disk Brake Conversion

If your C2 is a 1965 model or later, GM has already taken care of this conversion for you. If your C2 was produced prior to 1965, well… you have some catching up to do. GM made disk brakes standard on the Corvette in 1965 and hasn’t looked back since. This is for good reason. Disk brakes inherently carry much more immediate stopping power than their drum brake counterparts. The reason behind this gets somewhat scientific.

Braking is accomplished when pad or shoe surface media is placed in contact with the surface of a brake drum or rotor. When this occurs, kinetic energy is transferred into heat by way of friction. When brake surfaces have absorbed as much heat as possible and adequate dissipation can no longer occur, brake fade results. Brake fade is characterized by a loss in braking efficiency due to substantial heat. Because of the closed design of drum brakes, they are significantly more prone to the onset of this condition.

Performance Online Front Disk Brake Conversion Kit

Are you ready to bring your Corvette’s braking capabilities up to par? Look no further than Performance Online’s Front Disk Brake Conversion Kit. This kit has absolutely everything you will need at each front end wheel location to complete your conversion. One of the most appealing features of this kit is that the parts are sourced in a way that allows for easy future replacement of wear items. 1979-1986 Chevy Malibu calipers are utilized with this kit, making locating pads no more difficult than a trip to the corner parts house.

Also of appeal is this kit’s direct compatibility with stock spindles, making installation a snap. This kit comes complete with all mounting hardware, as well as the necessary bearings, seals, spindle nuts, and dust caps.

A/C Retrofit Kits

Although GM had started offering air conditioning as an option for the 1963 Corvette, very few buyers seized upon the opportunity. In fact, only 278 of the 21,513 Corvettes produced in 1963 had factory air conditioning. That as it may, the odds are better than not that you are sweating out the sweltering summer heat if you are an owner of an early C2 Corvette.

Lucky for those that have previously done without, A/C retrofit kits are widely available and can be had for any year model C2 that you might have. Although many of the mods on this list have centered on aspects of performance and drivability, let us not forget that a car that is unbearable to drive in the stifling summer heat and humidity is one that will often stay parked more often than its owner would like.

Classic Auto Air Retrofit A/C Kit

The Classic Auto Air Retrofit A/C Kit has you completely covered in the creature comfort department. This system features full electronic controls and industry-leading, separate heat and A/C coils, in contrast to the singular coils featured on most aftermarket units.

Updated Instrument Panels

To properly protect your Corvette from catastrophic engine failures, you must be able to accurately monitor the status of all pertinent engine functions. An overheating condition that goes unchecked can lead to a blown head gasket or other potential engine failures of the highest degree. Likewise, plummeting oil pressure can lead to a seized engine in mere seconds if its operator does not bring it to a halt.

What do these vital figures, among others, have in common? They are presented to a driver via the instrument panel. Second generation Corvettes utilized mechanical gauges that are widely known for their inaccuracies in any number of different vehicles. A sticking gauge can quickly leave a driver unaware of the state of their vehicle’s mechanical well being.

Alas, time has solved this issue as well in the form of modern electronic instrument panels. With a simple bolt-on replacement, you can now gain reliable gauge functionality for the overall benefit of your C2.

Classic Instruments Gauge Kit

Are you tired of sticking or sluggish gauges or wonder about the accuracy of your stock panel? Classic Instruments has you covered with this direct fit, electronic bolt-in replacement.

This Classic Instruments panel is also designed with a retro look as a nod to purists of the classic C2 stylings. The package also includes all necessary hardware and reuses your stock bezel.

This Classic Instrument’s unit is backed by a lengthy 5-year warranty and is priced to sell at a cost of $1.250.99.
