What is the difference between a Vortec and non Vortec engine?
Vortec heads are basically LT1 heads without the reverse coolant flow.
The port design is different that the standard SBC heads, but they fit one a Gen I small block as long as there is a Vortec intake manifold (the intake ports are taller).
The Vortec head is basically known for having really good flow at lower lift..
How long do Vortec engines last?
Overall, the 6.0 vortec is an extremely dependable and reliable motor. These engines frequently last beyond 300,000 miles with minimal issues beyond regular maintenance. However, making it to 300,000 miles will likely require some non-engine repairs and maintenance, such as suspension components.
What does Vortec stand for?
Vortec is a trademarked name for a line of engines for General Motors trucks. The name first appeared in an advertisement for the 1985 model year 4.3 L V6 that used “vortex technology” to create a vortex inside the combustion chamber, creating a better air/fuel atomization. Now it is used on a wide range of engines.

What is special about a Vortec engine?
The redesigned cylinder heads of a Vortec engine provides for improved combustion efficiency. The intake ports (reshaped) of the engine provides for better cylinder filling and fuel atomization by promoting higher air flow velocities to the combustion chambers via the ports.
Is the 5.7 Vortec a good engine?

How much power can you get out of a 5.7 Vortec?
the stock intake/ injector(poppet) assembly on your Vortec 350 limits powerto around 400 crank or 330 rwhp due to the restrictive intake and small 19 lb/hr injectors whuch cannot be replaced with larger pieces like other EFI systems, like LS1, LT1 and TPI.
