By this forums standards, "forever" is more than 45 minutes lol


If you check the board more than me, then your on here too much

Spoke to the guy I got my engine from today, he says their getting a 2008 Chevy Tahoe tomorrow that has the 5.3 and 4l65e with only 38k miles, says it is not a flex fuel... I'm trying to get him to give me that one but he says they normally get $3500 for those... He said he would try and see what he could do... I'm not getting my hopes up.

Someone set the car on fire for the insurance write off... Says no damage to the front end

Wow, that's crazy sorry to hear that but at least now she is the past... Lots of other fish in the sea... But if I end up with that drive train someone hooked me up... Probably won't happen tho

[desertdogg]

does anyone know what the difference is on the 4l65e vs the 4l60e ? He says this motor does not have flex fuel...was that an option ? just trying to get my ducks straight when I talk to him tomorrow

The 65 has internal upgrades over the 60, but don't think its all that much. Is it a 2wd? If not, I would pass on it since converting it to 2 wd would require almost a complete tear down.

Thanks Ls1, No he said it was a 2wd...but do you know if after a certain year they all went to flex fuel or was flex fuel an option ?

[dman1982]

i would guess misprint.....once again ill let the pros handle it man

[BR3W CITY]

Flex fuel was an option afaik, at least with the GenIII it used a different fuel rail and had the sensor that recognized what fuel it was being fed to adjust the computer map.

I was wondering about that, I think its a regular gas but is gen IV different than gen III In regards to flex fuel ? I believe 2007 is considered gen IV ? anyways I should get some more info on it friday morning.

[BR3W CITY]

There are both flex fuel and non flex fuel version of GenIV engines as well (can't comment on the differences in how it works, but both versions were available in 4.8-6.2l)

[ls1nova71]

In 2007 they made both gen3 and gen4 engines The new body style trucks got the new engine but they also made the older style trucks and called them silverado classics.. Also, it doesn't really matter if its flex fuel or not, they'll both run on gas. Do know that with a gen4, speedometers are harder to hook up and you loose the ability to use some features like DBW cruise control.

Dman your right it sure does, I sugested he give me 1500 back considering the mileage but he said he would rather trade me for a train with the originally quoted miles, or close to it. Im happy with it plus he says he already has the one he sent me sold.

Thanks Ls1, in that case I hope its a gen III...Ive read somewhere about losing the cruise control option but to be honest I probably wouldnt use it anyways I have CC on all my other cars and I rarely ever use it, but never heard about the speedometer deal curious as to why it would be different

Isn't the motor in your truck?...if so how's he going to sell something he don't have?...and who's going to buy the engine still in your truck when he don't even know what he sold you?....pull the pistons out of it and give it back to him for the troubles...haha

No, haha thank god its not in my truck yet, its been sitting in my garage since it was delivered...this all happened about a week after delivery just before getting ready to install it I ran a VIN search on it and it showed the off mileage he still swears the engine has 57k on it but I cant get proof so I dont want it. If that Engine had been installed I would have been really pissed off lol

Ok.. your on target. He did say it was a silverado classic so this is making sense.

[desertdogg]

Time for an update..I got tired of waiting for my engine to be delivered, so I decided to drive up to long beach and just go get my engine...to give him credit he tried hard to get someone down here but his boss didnt want to deliver it if there were no other deliveries...long story short its now in my garage and Im getting it to a friends shop where my suspension and drive train will be installed. Going to try to get it there tomorrow and hopefully in the next couple of weeks it will be done, well... almost done. Here are a few pics of my new engine. the date stamp code is saying it was made in 06 which I guess falls in line of being installed in an 07 Silverado. It looks a bit different and In my opinion looks to be newer than the last one so Im happy I ran a Car Fax on the Vin and last recorded mileage was 69K and some change the cluster odometer showed 72k... here are some pics Im hoping someone can tell me anything that jumps out at them.

fuel rails look a bit different...good bad ?

this is different looks like a heatsink of some kind ? anyone ?


one of what my truck looks like at the moment

[desertdogg]

Couple of more

[BR3W CITY]

Take her to the garage and tell her you can't go...cuz the engine fell out of the truck?
