Vortec? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Lynx · 03-13-2004, 01:20 AM

My friend has a 1986 GMC truck with a V-6 in it. He says it has a stock Vortec engine? Is this true?

r0lf- · 03-13-2004, 01:27 AM

Negative.

Destructo · 03-13-2004, 01:38 AM

I don't think the 4.3 was a vortec until 93 maybe?

Lynx · 03-13-2004, 01:41 AM

Well this is what i thought, then i did some searching and found This

Saying it started in 86 so am i going to be eating my words? (I told him he was wrong... lol)

**swervin ervin** · 03-13-2004, 02:03 AM

Vortec 4.3 V6's were fuel injected, and TPI injected I do believe. 4.3's in our trucks in 86 were not even TBI. TBI wasn't used in full size trucks until 87. Vortec 4.3's were used in S10's.

ElGracho · 03-13-2004, 04:26 AM

This has come up before. Just like the link to the GM site says, GM introduced the Vortec name in 1986. As for only being in S-10s, not so fast Mike, here is a scan from the 1986 Fullsize Chevy Truck brochure. It's not the vortec we like to think about now, but it's when GM started using the term...

**Captkaos** · 03-13-2004, 08:10 AM

The name Vortec came from the combustion chamber design. It was first used with the introduction of the 4.3L in 1986, so yes he has a Vortec in his truck.

*1FaastC10* · 03-13-2004, 12:01 PM

4.3s in S10s didnt start until '88

gldevall · 03-13-2004, 05:11 PM

You are correct Chris. The V-6 that I had in my 86 was a Vortec.

jordon johnson · 03-13-2004, 10:41 PM

the vortec did not start until 93 because my moms blazer is a 93 it has a 4.3L vortec and i looked at a 92 the other day it was a 4.3 it was not a vortec

**swervin ervin** · 03-13-2004, 10:50 PM

Jordan is correct on the L31 Vortec 4.3 V6 that came in S10's. This to me is the only one I count. I don't care what GM called the carbed V6's in the full size trucks.

i believe you're thinking of the L35 Mike, the L31 is the '96+ 5.7. 92 was the first year for the CPI 4.3, which is commonly referred to as the Vortec V6, although the TBI 4.3 was still available for 92 and 93, it disappeared with the body style change in 94.

**swervin ervin** · 03-13-2004, 11:04 PM

Damn it!! I was thinking of Vortec heads when I typed that.

I'm really not as stupid as I look.

Yeah and it's hard to type with your left hand while your right one is hurting like hell.

Not been one of my better weeks for sure.

*1FaastC10* · 03-13-2004, 11:19 PM

oh, i forgot about that!

gldevall · 03-14-2004, 01:23 PM

I think the pain killers count too.

*1FaastC10* · 03-14-2004, 04:18 PM

another note... the first Vortec 4.3 engine wasnt even injected, it carried a Quadrajet on a cast iron manifold.

ElGracho · 03-14-2004, 10:55 PM

Someone please kill this thread.

*1FaastC10* · 03-14-2004, 11:07 PM

why would you want to do that?

maybe we should kill every thread that comes up about special edition trucks too, cuz they r gay!

Lynx · 03-14-2004, 11:10 PM

Not sure whats wrong with the thread... might have gotten alittle off topic there but ohh well.

So they guy most likely has a Vortec, but its carborated and has a castiron intake, and is just not what one would normal consider a vortec like those that are around now/ early ninties

ughh, sure.

This thread started with a question:

Several people said no because it wasn't fuel injected, a few people said yes and linked to GM information, and a few several people said 'not in my opinion'. Now we're back to repeating information that is just a few replies up in the thread and should move on to new things.

**swervin ervin** · 03-15-2004, 01:30 AM

I guess since we don't all agree and some of us have opinions we should close the thread because you don't like what is being said???

ElGracho · 03-15-2004, 01:41 AM

If you go back to the original question, it's been answered (and by the original poster I might add). Talking about it more is pretty much a waste of bandwidth. I see this turning into a flame war and I really don't want that.

When it comes down to what mother GM wants to call her engines, who are we to argue?

*1FaastC10* · 03-15-2004, 03:00 AM

i think a nice STFU is in order...
