What should I consider before choosing a Chevy 350 distributor?

Feature #1: Design

To select the right distributor for your Chevy 350 based on design, you need to pay attention to some facts. First, don’t go for Aluminum terminals. Instead, choose the brands with brass terminals.

Brass is known for good conductivity and durability while Aluminum will not last long. Also, pay attention to the distributor caps. Don’t place appearance over functionality in making this decision.

A simple cap might last longer compared to flashy-looking types. Also, the rotor should be designed to minimize electric arc production as much as possible. If you drive your Chevy 350 frequently or in races, select a distributor whose rotor can withstand tough driving and corrosion.

Feature #2: Compatibility

If you need a new distributor that will work for your Chevy 350, take note of the dimensions of the old one. Then, use a screwdriver to remove the current one in your vehicle. Check the length and the number of gear teeth. It should be identical to the new one you want to install.

These two specifications are important. Also, you need to verify whether you have a big or small engine block. Moreover, this factor affects the compatibility of any distributor you want to buy.

Feature #3: Power

You should consider the electrical output of the distributor you want to purchase. A high voltage of 65,000 volts and a speed of 7,500 RPM should be perfect for any application. However, your budget should also come into the picture here.
