How much power does a 454 engine make?

How much power does a 454 engine make?

Surprisingly, the 454 laid down an impressive 330 horsepower and 475 pound-feet of torque. Naturally, the truck-based 454s were tuned for torque, so having nearly 500 pound-feet wasn’t a big surprise. But like any stock engine, there was tons of power left to be squeezed out.

How much power can a 454 Block handle?

They claim the experts agreed that about 700-750 hp is all a stock bottom end 454 could safely handle.

What kind of gas mileage does a Chevy 454 get?

The 454 is a big-block carbureted engine found in most older model Chevrolet cars and trucks. The engine uses eight cylinders to provide high-end torque and speeds. The combination of larger bore and eight cylinders equates to very poor gas mileage. The engine runs an average of 10 to 15 mpg.

What makes the Chevy 454 7.4L engine unique?

The return of the 231 V-6 to General Motors cars in the mid-1970s proved that fuel efficiency could be achieved in compact engines. But in 1988, Chevrolet introduced Throttle Body Fuel Injection to the 454. It was the same TBI system used on small-block V-8s and the V-6s. Fuel efficiency increased and the TBI system remained until 1995.

What is the fuel consumption of a 454 Crusader?

I looked in the library and saw that the fuel consumption for a 454 Crusader running at 3,200 RPMs is listed at 14.7 GPH. Mine are 1983 model year. My 38 Commander was repowered with 454’s.

What should the temperature be in a 454?

Engines run at a steady 165 – 170 degrees per the temp gauges and heat gun at this speed which I am told is normal for 454s. The motors take a little pumping of the throttle to start, but run and idle fine right at 600 – 800 RPM idle.

When did Chevy stop making the 454 engine?

Unfortunately the Chevy 454 was the right engine at the wrong time. Uncle Sam started to tighten down on emission controls in 1971 which affected a lot of the power of the 454. Another big blow for the 454 was the gas crisis of 1973 which pretty much sealed the fate for the motor during this period.
