how can you tell a real 1966 nova ss 327 l79 from a clone?
Great question! The 1966 Nova SS 327/L79 is one of the most cloned muscle cars out there because it’s relatively easy to turn a base Chevy II 100 into a “tribute” machine. Here’s how to separate the real-deal L79 cars from the fakes:
The first three digits are your best friend:
| Code | What It Means | Authentic SS? |
|---|---|---|
| 118 | Super Sport V8 | ✅ YES - Real SS |
| 116 | Nova V8 (non-SS) | ❌ No |
| 114 | Chevy II V8 (non-SS) | ❌ No |
| 113 | Chevy II 6-cylinder | ❌ No |
This car (118376N170504) has the “118” prefix - that’s your first green light! The “6” confirms 1966, “N” is Norwood assembly, and “37” means 2-door Sport Coupe.
Real L79 327/350hp engines have a VIN derivative stamped on the block plus a date/suffix code. For 1966 L79 Novas, you’re looking for codes that should match something like:
⚠️ Red flags:
These were ALL standard with the L79 package—no exceptions:
| Feature | Why It Matters |
|---|---|
| Muncie 4-speed | The L79 was only available with manual trans |
| 12-bolt rear axle | Required for that torque (3.31 gears standard) |
| Front disc brakes | Included with L79 |
| Dual exhaust | Part of the L79 package |
| Holley 4-barrel | Special high-rise intake, 650 cfm carb |
Real L79s got the famous “camel hump” or “fuelie” heads with 2.02” intake/1.60” exhaust valves and proper casting numbers. These are physically different from standard 327 heads.
Only 5,481 L79 Novas were built in 1966—compare that to over 13,000 standard 327 SS models. If a seller claims “numbers matching” but the price and story seem too good to be true… dig deeper!
The listing vehicle (VIN 118376N170504) starts with the correct “118” code, so it began life as a true Super Sport. However, as noted in the FAQ, the engine stamp pad photos aren’t shown—that’s something you’d want to verify before buying any L79 claimed as original. The listing mentions a Holley 4-barrel and Muncie 4-speed, which aligns with correct L79 specs.
