5.3L EcoTec3 V8 Engine
As you can see, the figures show that the 2.7L Turbo engine generates more torque than the 5.3L V8 when comparing the 2.7 turbo engine vs. 5.3 Silverado. However, the latter comes out ahead in terms of horsepower.
Which is better 327 or 350 engine?
The bottom line here is simple; no matter what you do to a 327, if you do the same thing to a 350, it WILL make more horsepower and torque than a 327 will, period. The same thing goes with ANY engine when comparing cubic inches and power, especially when you are talking about making more torque with longer strokes.
Is a 5.3-liter engine a 327?
The gm 5.3 is a 325. It has nothing to do with the old 327.
How much horsepower does a 5.3 Chevy engine have?

Is there a problem with the Chevy 5.3 engine?
Problem: One of the issues in the Chevy 5.3 engine was coolant loss. This trouble emerged from a cracked cylinder head, which allowed coolant to flow out during the transaction process instead of going through every component and doing its job. In time, this coolant leak could become a critical issue.
What is the difference between a 5.3 and a 2.7 turbo?
The standard 5.3L engine offers more horsepower, while the 2.7L offers more torque and a higher rate of 3,000 RPM. This makes it a more efficient choice than the standard engine, though not quite as powerful. Both engines have identical towing capacities, while the standard 5.3L engine can handle a bit more payload.
What is the life expectancy of a 5.3 L engine?
Reliability and Longevity of the 5.3L V8 Engine
Chevrolet's 5.3L engine is touted for its reliability, having the potential to exceed 200,000 miles with proper care. Factors influencing longevity include regular maintenance and driving habits—key components to getting the most out of this durable and trusted engine.
Is Chevy 5.3 V8 a good engine?
like the rest of the LS family, the 5.3 is one of the best V8 engines on the market (certainly at least as good as competing domestic V8 families). I don't have the weight figures but I would be VERY surprised if the high feature V6 or any other large OHC V6 is appreciably lighter.
