How much horsepower does a 1983 Z28 have?

The 1983 Camaro Z28 delivered about 165 horsepower (SAE net) from its 5.0-liter V8. This article looks at that figure, how it was measured, and what it meant for performance at the time.

For context, horsepower numbers in the early 1980s GM cars were calculated using SAE net ratings, which reflect the engine with standard accessories and exhaust. This makes the official figure lower than the older gross horsepower numbers commonly referenced in earlier decades.

Engine and power basics

The single most important factor for a 1983 Z28's power rating is the 5.0-liter V8 model that year. It used carburetor induction and was tuned for reliability and emissions compliance in the era.

Key specifications that influence the horsepower figure are listed below:

• Engine: 5.0 L (305 cu in) V8


• Induction: 4-barrel carburetor


• Horsepower: 165 hp SAE net


• Torque: approximately 275 lb-ft


• Transmission options: 4-speed manual or 3-speed automatic

The above figures reflect typical builds for the 1983 Z28; exact output could vary modestly by production batch, emissions calibration, and market region.

Context on rating methods

GM's move to SAE net horsepower in the early 1970s and the subsequent 1980s meant the official numbers included power losses from accessories and exhaust. This is why the quoted horsepower for the 1983 Z28 sits around 165 hp rather than the higher gross figures sometimes seen in older literature.

Details about how horsepower is reported and what factors can influence the numbers are shown below.

• SAE net horsepower: 165 hp (1983 Z28 5.0 L V8)


• Torque: around 275 lb-ft


• Possible minor variation by late-1983 production


• Regional or documentation differences can yield small discrepancies in horsepower claims

In short, the official 1983 Camaro Z28 figure centers on 165 horsepower with roughly 275 lb-ft of torque, as measured by SAE net standards of the time. Real-world performance also depended on gearing and condition.

Summary

The 1983 Z28's power rating of about 165 horsepower (SAE net) from the 5.0-liter V8 was typical for third-generation Camaros of that year. While variations existed across individual cars and markets, this figure serves as the standard reference for the model in 1983.

How much horsepower does a 1984 Z28 Camaro have?

Under the hood, the 1984 Camaro Z28 was equipped with a range of powerful engine options that catered to different performance preferences. The base engine was a 5.0-liter V8, which produced 150 horsepower and 240 lb-ft of torque.

How much is a 1983 Z28 worth?

A 1983 Camaro Z28's value varies significantly based on condition, mileage, and specific features, but generally ranges from around $7,000 to over $13,000 for a good-condition vehicle. Exceptionally well-maintained examples or those with rare options can fetch prices as high as $22,000-$34,650 at auction, while those with major needs might be found for under $8,000.
 
Value breakdown

• Average Condition: Approximately $7,000–$13,000. Prices can be expected to be around $7,200 for a typical example in good condition, but valuation tools show averages closer to $13,167 for good examples. 
• Excellent Condition: Over $20,000 is possible, especially for low-mileage cars or those with sought-after options. High auction prices have reached over $30,000 for the best examples. 
• Poor Condition: Prices can be as low as $7,875, particularly if the car requires extensive maintenance, has accident history, or has been heavily modified. 

Factors that influence value

• Condition: The overall state of the car, including body, interior, and mechanicals, is a primary factor. A rust-free, accident-free car with good paint and a well-running engine will be worth much more than one that has been neglected. 
• Mileage: Lower mileage generally means a higher value. A 3,400-mile example sold for $33,000, while a 69,000-mile one might be in the $17,000 range. 
• Options and Engine: The original engine and specific factory options can significantly increase the car's value. For example, a manual 5-speed transmission is often more desirable than an automatic, and a 350 engine would be more valuable than a 305. 
• History: A clear vehicle history with no accidents or title issues adds to the car's value. Modifications can either increase or decrease value depending on how they are done and if they appeal to the buyer. 

How much horsepower does a 1982 Z28 Camaro have?

The 1982 Camaro Z28 had two V8 engine options: the standard 145 horsepower, 5.0L carbureted engine, and the optional 165 horsepower, 5.0L Crossfire fuel injection engine. The Crossfire engine was only available with an automatic transmission, while the base carbureted engine was paired with a standard four-speed manual transmission.
