Spotting Guide: Tri 5 Chevys
The differences between '55, '56 & '57 Chevys
Tri-5 Chevys are some of the most popular body styles in the Resto-Mod and Antique(Stock) scenes. Ever confuse the years on these classic Chevys? Well, let's take a look at a few of the more obvious differences between the three years. I'm not going to get bogged down in the minor differences like ashtrays, interior window rings or engine crank strokes, just the things that will help you confidently identify the three different years of this popular car!

All new for 1955! Notice the grille in this car. The key to identifying most American made early cars is all about the grille! The rectangular grille with rounded corners is the thing that instantly tells you this is a '55 Chevy! Also, notice that this car has no rear tail fins.

The differences between the '55 and the '56 in the grille are huge! Notice the '56 grille has no rounded corners, larger parking lights under the headlights and chrome trim that wraps around to the fenders. '56's also have no rear tail fins.

This is the most dramatic difference of the 3 years. Most noticeable is the center grille bar, with parking/turn signal lights. The bumper is also more shapely and includes rubber bumperettes. Larger headlight rings are present. This cars rear tail fins are easily seen from the front of the car.
3 Points of Interest:
1955 was the debut of Chevrolets OHV V-8 engine. Chevrolet had been using the same straight 6 engine in both their car and truck line ups since 1929! This new V-8 engine would come to be known as the Small Block Chevy, or SBC. Chevrolet would produced a variant of the same '55 engine until 2003. Once the final numbers were added up, over 90 million of them were made.
In 1956 Chevy spent over a million dollars coming up with a new design for 1957. They wanted the car to look more like a Cadillac. That's were the tail fins came from!
Oil filters were not standard equipment for the 1955 model year.
