Does vortec engine mean good?
Hi, I was looking at a minivan - astro or safar. Is the 4.3 Vortec a
good engine? I just see it as a plus in the ads and wanted to know. Especially since they are higher in miles (at least the ones I can afford). Thanks. |

More or less just a trade name. Steve > wrote in message oups.com... > Hi, I was looking at a minivan - astro or safar. Is the 4.3 Vortec a > good engine?

Is GM licensing the technology to others or is that just someone else using a similar name for similar technology. I am under the impression that this is GM's method to ensure lots of turbulence in the combustion chamber. Is this right? |

VTEC, if that is what you are refering to, is a whole other ball of wax. VTEC is purely a Honda trademark name, but does mean something; Variable valve Timing and lift Electronic Control. The actual non-trademark acronym would be VVT; Variable Valve Timing. Learn all about the differecnt types and associated trade names he http://en.wikipedia.org/wiki/VVT > I am under the impression that this is GM's method to ensure lots of > turbulence in the combustion chamber. Is this right? I doubt it's nothing more than a trade name, period. Like the way GM says "Ecotech" or Ford says "PowerStroke" or the way Chrysler now uses the term "Hemi." Doesn't really say anything about the engine, it's just a name. (Before this causes a ruckus, look it up. They are no longer true "hemi's". They are as much of a Hemi as my '95 GM 3.4L DOHC is.)

The Vortec name specifically refers to the cylinder heads. This article explains it pretty well: http://www.chevymania.com/tech/vortec.htm |

The modern 5.7 Hemi is "more" of a Hemi than any quad-valve DOHC engine, though. Quad-valves are pent-roof chambers. |

True, I should have thought it over before typing. My point was, which I think was conveyed, is that the new 'Hemi' name is more marketing than design. And as pointed out by a previous poster this is not 100% true of the 'Vortec' brand as I stated earlier. Steve |
