Admin Are all 350 Vortec heads the same?
Vortec Means Power Vortec heads instantly added 55 or more horsepower to a regular 350 head with the same displacement. Automotive enthusiasts are quick to note that the 350 and the 5.7 Vortec are essentially the same engine with the same displacement.
What is the difference in Vortec heads?
Types of GM Vortec Heads The Vortec heads are a little bit lighter than the older heads and have a “kidney” or “heart” shaped combustion chamber that is more efficient than the double hump chamber.
What years were Vortec heads made?
From 1996 to 2000, GM truck and van 350 engines came equipped with L-31 Vortec cylinder heads. Built of cast iron, these powerhouse heads upped the horsepower of these engines by magnitudes.
What CC are Vortec heads?
These large chamber heads shrouded the valves even more than the older 64-cc chambers and did nothing to improve airflow. Not so ironically, the Vortec returned to a 64-cc chamber mainly because the current trend for all engines is with smaller, tighter chambers to improve both flow and chamber activity.
What is the difference between 350 heads and 350 vortec heads?
5.7 Vortec Heads and Regular 350 Heads The intake port of the Vortec head is different and measures 160cc with a modified port that increases the flow velocity. The bowl area is wider around the guide compared with regular 350 heads. The intake bolt pattern is different and utilizes an eight-bolt attachment.

Will a V6 engine harness work with a V8 engine?
First of all, you can USE your v6 engine harness to run the v8. It should fit just fine. You do need to add two additional injector wires to the PCM, and two key hot power wire to the injector connector. Of course you need to change out the large injector connector. The V6 PCM can also be reprogrammed for the V8 engine.
