Muscle Car Of The Week Video Episode #179: 1967 Shelby GT500 427 Side Oiler

The ‘65 and ‘66 Shelby Mustangs were very successful cars, but Shelby upped the stakes for ‘67 by introducing a big-block version of the GT cars with the GT500. However, this one takes it up another notch with a 427 "side-oiler" V8. From The Brothers Collection.

The 1967 Shelby GT500 was a significant evolution from its predecessors, transitioning from the initial track-focused design to a more refined and comfortable muscle car. Here are some key points about the 1967 Shelby GT500:

1. *Evolution of Shelby Mustangs:* The 1965 GT350 was renowned for its raw power and performance, but over time, the Shelby Mustangs, including the 1967 GT500, evolved towards greater comfort and style to appeal to a broader market. However, they still retained impressive performance capabilities.

2. *GT500: A Shift Towards Comfort:* The 1967 GT500 was a more refined version compared to its predecessors, catering to the mass market's preferences. It featured additional comfort and style elements while maintaining its performance pedigree.

3. *Engine Transition: 428 to 427:* While the 1967 GT500 originally came with a 428 V8 engine, some owners opted for a swap to the more high-strung 427 side oiler due to the 428's reliability issues under hard driving conditions. This swap was relatively easy due to the similarities between the two engines.

4. *428 Police Interceptor vs. 427 Side Oiler:* The 428 in the GT500 was a modified police interceptor engine, delivering 355 horsepower and 420 pound-feet of torque. In contrast, the 427 side oiler was a high-performance racing engine with higher compression, tighter tolerances, and a solid mechanical valve train, resulting in a nastier idle and more power at higher revs.

5. *Authenticity and Modifications:* While purists might argue for authenticity and the importance of having the original 428 engine, the 427 side oiler offers a different driving experience and performance characteristics. This specific GT500, despite not having its original engine, showcases a choice that aligns with the spirit of Shelby's high-performance ethos.

6. *Design and Features:* The 1967 GT500 underwent various modifications, including fiberglass nose pieces, unique body features, and distinctive styling elements like the sequential taillights.

Ultimately, the preference between the mellow 428 and the high-strung 427 boils down to individual driving preferences and appreciation for authenticity versus modified performance. Both engines have their merits, offering distinct driving experiences in the iconic 1967 Shelby GT500.
