did chevy replace the 3500 for the 3600 that was out longer than the 350. i had the 3600 in my 88 blazer befor i junked it body and frame was shot thats why i got rid of the blazer. but did chevy git ride of the 3500 for the 3600? i dont see the 3500 motors in that many vehicles any more.

 

I would hope so, but again I don't think so. If you're referring to the 3600 that's in the new V6 Camaro...I'm not sure if I can see a 304HP v6 powering most of their fleet of cars, the 3500 is more fuel efficient.

 

thing is i was at the dealer on friday getting my rear controll arms fixed. there is some of the fleat that have the new 3600 in it i forgot the fuel rating though.

 

...Hi `John,
Check out the below link on GM Engines. Hope it helps

my question is it seems like the malibu the impalla and some of the mid size cars from gm are going to the 3600that is what i was saying it seems like the 3500 is on the way out the door. i am wondering is the 3600 has the same bottom end like the 3500. because it is simular to the 3900 and the 3500 vvt flex fuel type

 

The 3600 is a DOHC engine. The 3500 and 3900 are OHV engines. They are not similar in either design or function. The 3600 is GMs new "high feature" V6. It is a completely new design and I dont think it shares design with any other GM engine prior to its release. What 3600 are you talking about that was in your 88 blazer? The 3600 wasnt introduced until 2004.

 

it was actually the 3.8 v6 sorry and was thinking of fords 3.6 v6 that they used for the longest time.

 

As Matt said, the NEW 3.6L has nothing in common with the 3500. The 3.6L is a DOHC 24V design, and the 3500 is a pushrod 12V.

As far as the 3.6L replacing the 3500, I definitely see that happening. Why wouldn't GM get rid of a 211 HP V6, and replace it with a 304 HP V6 that gets almost the same gas mileage? The 3.6L IS fuel efficient, almost the same as the 3500/3900 engines. The thing is, GM is mating the 3.6L to a 6 speed tranny in the applications where its being used. This makes the power of the 3.6L available when needed, while also allowing them to achive gas mileage as high as 29 MPG HWY. Based on the NEW 2008 EPA estimates, the 3500 with the 4 speed auto they mate it to gets 29 MPG HWY. Keep in mind these are numbers from the new, harsher EPA estimates that were put into affect in 2008. I have got more than 29 MPG out of my 3500, but its on rare occasion, just like i'm sure the 3.6L CAN get more than 29 MPG, just not all the time. The new 2008 EPA estimates are just more realistic.

 

The 3800 was estimated at 19city/29highway...then over 10 years later they introduce the 3.6 with the same fuel consumption. Granted, it has 104HP more than the 3800, but there wasn't an increase in fuel efficiency it seems. Maybe I'm missing something, but I don't know if this was the best step.

 

Well you nailed one of the points, it makes 104 HP more, so a way more powerful engine, with the same fuel economy. Isnt this exactly what America wants? More power, but good gas mileage. I think the 3.6L acheives that very well.

Plus the 3.8L was rated on the old scale for EPA the new scale rates it at 17-27, while the 3.6L on the new scale is at 19-29. So it is a smidge better.
