In this guide, we will break down the 1995 chevrolet camaro z28 specs so you can diagnose issues, perform upgrades, and maintain peak performance.

From the intricacies of the reverse-cooling system to the legendary T-56 six-speed transmission, we are going to cover every nut and bolt. By the end of this article, you will have the confidence to tackle everything from a basic tune-up to a full suspension overhaul.

1995 chevrolet camaro z28 specs

When we look at the 1995 chevrolet camaro z28 specs, the centerpiece is undeniably the 5.7L LT1 engine. This was a significant leap over the previous L98, featuring a reverse-flow cooling system that allowed for a higher compression ratio of 10.4:1.

The engine uses a cast-iron block with aluminum heads, providing a balance of durability and weight savings where it counts. It features a 4.00-inch bore and a 3.48-inch stroke, which is the classic 350 cubic inch displacement formula that Chevy perfected over decades.

Fuel delivery is handled by a Sequential Fuel Injection (SFI) system, which was more precise than the batch-fire systems of earlier years. This allows for smoother idling and better throttle response throughout the RPM range, making the 1995 model a favorite for street driving.

Engine and Power Output

  • Engine Type: 5.7L V8 LT1
  • Horsepower: 275 hp @ 5,000 rpm
  • Torque: 325 lb-ft @ 2,400 rpm
  • Valvetrain: OHV, 2 valves per cylinder
  • Firing Order: 1-8-4-3-6-5-7-2

Fluid Capacities and Recommendations

For the DIY mechanic, knowing your capacities is essential before you start draining fluids. The LT1 requires 5.0 quarts of 5W-30 motor oil with a filter change, though many high-mileage owners prefer 10W-30 in warmer climates.

The cooling system is unique and holds approximately 15.3 quarts of a 50/50 mix of ethylene glycol and water. Always remember to bleed the system using the brass screws on the thermostat housing to prevent air pockets that lead to overheating.

Transmission and Drivetrain Engineering

The 1995 Z28 offered two main transmission choices: the 4L60E four-speed automatic and the T-56 six-speed manual. The 4L60E is electronically controlled, meaning its shift points are determined by the Powertrain Control Module (PCM).

The T-56 manual is the enthusiast’s choice, featuring a dual-overdrive setup that allows for high-speed cruising at low RPMs. One quirk of the T-56 in this year is the Computer Aided Gear Selection (CAGS), also known as “skip-shift,” which forces a 1st-to-4th gear shift under light throttle to save fuel.

Power is sent to the rear wheels through a 7.625-inch 10-bolt differential. While sufficient for stock power levels, this rear end is often the “weak link” if you plan on adding forced induction or sticky drag radials at the track.

Gear Ratios and Final Drives

  1. Automatic (4L60E): 3.06 (1st), 1.63 (2nd), 1.00 (3rd), 0.70 (4th). Standard rear gear is 2.73, with 3.23 as an option (Performance Axle G92).
  2. Manual (T-56): 2.66 (1st), 1.78 (2nd), 1.30 (3rd), 1.00 (4th), 0.74 (5th), 0.50 (6th). Standard rear gear is 3.42.

If you are looking for more “punch” off the line, upgrading a 2.73 automatic car to 3.42 or 3.73 gears is one of the most effective 1995 chevrolet camaro z28 specs modifications you can perform. It completely changes the car’s personality.

Chassis, Suspension, and Braking Systems

The 1995 Camaro utilized a Short-Long Arm (SLA) front suspension design. This was a major departure from the MacPherson struts used in the third-gen cars, offering better camber control during hard cornering.

At the rear, you will find a live axle setup supported by a massive torque arm, two lower control arms, and a Panhard rod. This setup is excellent for putting power down in a straight line but can feel a bit “lively” on bumpy mid-corner pavement.

Braking is handled by four-wheel discs with a standard Anti-lock Braking System (ABS). The front rotors are 10.7 inches, which is one area where the car shows its age; many owners opt for the “LS1 brake swap” from later models for better stopping power.

Wheel and Tire Fitment

Standard Z28s came with 16×8-inch “five-spoke” aluminum wheels. The factory tire size was 235/55R16, but many came equipped with the 245/50ZR16 performance tire option.

If you are upgrading your wheels, the F-body chassis can easily swallow a 17×9.5 or even 17×11-inch wheel in the rear with minor modifications. This is vital for maintaining traction once you start tweaking the 1995 chevrolet camaro z28 specs for more power.

The Optispark and Electrical Nuances

We cannot discuss the 1995 Camaro without mentioning the Optispark distributor. Located behind the water pump, this unit is notorious for failing if it gets wet. In 1995, Chevrolet introduced a “vented” version of the Optispark, which was a huge improvement over the 1993-1994 units.

The vented system uses vacuum lines to pull moisture out of the distributor cap, significantly extending its life. However, if your water pump starts leaking from the weep hole, it will drip directly onto the Optispark, causing misfires or a “no-start” condition.

Another unique feature of the 1995 model year is the “hybrid” OBD system. It uses a 16-pin connector (like OBD-II) but typically runs on OBD-I protocol. This can be confusing for DIYers trying to pull codes, as a standard OBD-II scanner often won’t communicate with the car.

Electrical Pro-Tips

  • Check the Harness: The pigtail connector for the Optispark often becomes brittle. Always inspect the clips when doing a tune-up.
  • Ground Straps: Ensure the engine block ground strap (located near the starter) is clean and tight to prevent erratic sensor readings.
  • Battery Placement: The battery is tucked under the passenger side cowl. Always use a Group 75 side-post battery for the best fit.

Common Maintenance and Troubleshooting

Maintaining a 1995 Z28 requires a proactive approach. One of the first things I check on any LT1 is the condition of the vacuum lines. The rubber tends to crack after nearly 30 years, leading to lean conditions and rough idles.

The cooling system is the second priority. Because the LT1 is reverse-cooled (heads first, then block), it is extremely sensitive to air pockets. Always use the bleeder valves on the cooling lines while refilling the radiator to ensure the system is pressurized correctly.

If you experience a “stumble” under load, check your spark plug wires. Because they are routed underneath the exhaust manifolds, they are prone to heat damage. Using a high-quality set of 8mm or 8.5mm silicone-insulated wires is a smart investment for any DIY mechanic.

Diagnostic Checklist

  1. Fuel Pressure: Should be 41-47 PSI with the key on and engine off.
  2. TPS Voltage: Should be around 0.67V at closed throttle.
  3. IAC Counts: If the idle is hunting, the Idle Air Control valve likely needs cleaning or replacement.

Frequently Asked Questions About 1995 chevrolet camaro z28 specs

Is the 1995 Camaro Z28 OBD-I or OBD-II?

The 1995 model is a “transition year.” It features the 16-pin ALDL connector associated with OBD-II, but the PCM (computer) still operates on OBD-I logic. You will need a specialized cable or a scanner capable of reading OBD-I through a 16-pin port to access data.

What is the 0-60 mph time for a stock 1995 Z28?

In stock form, a 1995 Z28 with a 6-speed manual could hit 0-60 mph in approximately 5.7 to 6.0 seconds, with a quarter-mile time in the low 14-second range. These were very respectable numbers for the mid-90s and still feel quick today.

Can I use Dex-Cool in my 1995 Camaro?

While GM transitioned to Dex-Cool shortly after, most 1995 models came with the traditional green ethylene glycol. It is generally recommended to stick with the green coolant unless the system has been completely flushed and all gaskets have been updated to Dex-Cool compatible materials.

How much horsepower can the stock 10-bolt rear end handle?

The stock 10-bolt is generally safe up to 350-400 rear-wheel horsepower, provided you aren’t using “slicks” at a prepped drag strip. The most common failure point is the pinion gear or the carrier bearings under extreme shock loads.
