The LT1 is a Chevrolet small-block motor part produced by the Chevrolet Division brand, which belongs to General Motors. This term first appeared in the period between 1970 and 1972.

Up to the present, this kind of engine has still been available in the vehicle lineup manufactured by the Camaro and Corvette.

It is considered one of the greatest Chevy small-blocks among all the engines in production since 1955.

During its history, General Motors manufacturers have released a total of three different engines called LT1:

  • Chevrolet Generation I small-block (1970 – 1972)
  • Chevrolet Generation II small-block (1992-1997)
  • Chevrolet Generation V small-block (2013 until now)

What Are The 1994 LT1 Engine Specs?

The 1994 LT1 engine specs are specifications for the small-block engines manufactured in the year of 1994. The specs differ in different models, like Chevrolet, Pontiac, Buick, and Cadillac.

Below are some different applications of this engine model’s specs.


As presented above, the LT1 engine was primarily used in the Chevrolet models, including Camaro Z28, Impala SS, Corvette, and Caprice Wagon.

Depending on each vehicle, this engine could display different capacities given the horsepower and pounds of torque.

  • For the Camaro, the LT1 engine can produce 325 torque pounds and 275 horsepower.
  • For the Corvette, the LT1 engine pumps out a power output of 300 horsepower and around 340 pounds of torque.
  • For the Caprice Wagon and Impala SS, the LT1 engine produces 330 torque pounds, along with 260 horsepower.

Regarding its design, this engine bears a resemblance to the original design no matter what car brands it is used. Its components include a 4-inch bore and a piston stroke of 3.48 inches.


Pontiac has applied the LT1 engine in its two automobile series: the Trans Am and Firebird Formula.

Unlike the Chevrolet, its capacities are similar regardless of being used in any of the two models. It can produce roughly 325 pounds of torque and 275 horsepower.

There is no difference between the LT1 engines utilized in the Pontiac compared to that of the Chevrolet.

It contains a 4-inch bore and a 3.48-inch piston stroke. When it comes to compression figures, the ratio stands at 10.5:1.


Buick has used the LT1 engine in the Roadmaster model, a full-sized sedan. Its capacities and design are no stranger to that of Caprice Wagon.

It can produce up to 330 torque pounds as well as 260 horsepower. Its manufactured components also include a bore and a piston stroke with mentioned sizes and scales.

The LT1 pushes the Roadmaster to 25 mpg while driving on the highway and 17 mpg on the city street.


The Fleetwood of Cadillac has used the old versions of the LT1 engine, a 4.6 Northstar engine, and a 5.7 liter LT1 engine. It can produce approximately 260 horsepower and 330 pounds of torque.

Statistics about piston stroke and bore sizes are the same as those used in Buick. This engine has got 17 mpg within the city and 25 mpg on the highway.

350 lt1 engine horsepower

Yes, the 1994 Chevrolet Camaro Z28 LT1 is considered a good engine. Let’s check some LT1 engine specifications for this car model to see how it performs.

Powertrain Engine

The powertrain engine of the Camaro ZS8 is a 396i small-block, whose design is based on the forged Eagle.

It has a crank of nearly 3.9 inches, an H-beam rod of 6 inches, together with flat-top pistons.

It also has other components, including valves, cane rocker arms, and long-tube aluminum heads.

Another plus lies in the Cam Motion device, which can capture tiny movements and notice minor signals transferred via the wiring network.


The LT1 engine can produce around 367 foot-pounds of torque and 456 horsepower at 6800 rpm.


The transmission device is a TH350 model, replacing the old-fashioned one, 4L604E.

Many drivers reported that their 4L604E had encountered many problems during its operation, so the Camaro brand decided to make some modifications.

Rear End

The GM 10-bolt device of roughly 8 inches has been reported to explode many times under hot temperatures.

So in the 1994 model, Camaro had replaced it with a new part called Moser 12-bolt with 4.10:1 gears and 33 axles of spline.

Chassis Frame

There seems to be no change in the chassis frame. The frame is still stock other than the equipment of a Wolfe Racecraft roll bar.


The 1994 Camaro ZS8’s suspension parts include several components: spring-up front, torque arms, stock springs, QA1 shocks, rear trailing, and A-arms.


The braking system has pistons responsible for supporting the manual master cylinder.

Unlike old models, the Camaro ZS8 released in 1994 had no ABS system because it was removed, but the rest was still stock.


Cameron chose the Weld Pro Stars for its wheels’ partner, measuring 15×3.5 in front and 15×10 in the rear.


The ET Drags tires are famous for their quality and durability. They have been trusted by various car manufacturers in the world, and Macaron is not an exception with a scale of 30×9.

Style Body

Everything remained unchanged apart from the cowl-induction hood and fiberglass.


The cabin is very light, just about 500 pounds. There is AutoMeter fuel pressure, along with vacuum gauges on the driver and passenger’s seats.
