6.0/4l80e

[Hart_Rod]

Has anybody put this combo in our trucks? I've got a line on one but I want to make sure it will fit. I know someone has installed 6.0/4L60E, but 4L80E is a bigger tranny, so I'm wondering if I'm going to have clearance problems. I'm using the ECE motor mount setup.

Anyone????

[Joe67]

Engine will fit, no problem There is a member here running the 5.3l from a Chevy SSR as well as a few other LS1 based blocks in the classic trucks.

I don't know about the transmissions though.

I have that combo in my wife's daily driver. It's the factory combo though. It's a 2003 Chevy Express. It is an awesome engine. People can't believe a gigantic van can move like it does and it tows my ridiculously big camper like a champ. As stated, it will fit and it will get pretty decent mileage. We get 15 mpg unloaded around town. I get 10 mpg pulling my camper.

[Hart_Rod]

Thanks for info. Rob

I don't think you'll have much issue with tranny but I can't remember which oil pan complicates things. I thought it was the truck pan. I'm using a F-body set up. I've got a new 'vette pan if you run into issues.

[FirstGen]

I've got the truck pan in mine, fits great but it is lower than the crossmember which is a concern if you are seriously lowered.

[saulgoode]

This guy did it. Not a lot of info, but some pics and a cool break down of cost.

[ed455]

Motor is good, but sure looks ugly.

[68Stepbed]

I heard of a guy that put the 8100 Vortec/4L80E combo in a truck. There wasn't a lot of info on how it fit though.

BTW in case anybody was wondering, the 8100 Vortec is just a 496 BB with Vortec FI.

Don't know if this helps any, but thought I would post anyway.

"2001 Vortec 6000 6.0L Engine Baily Chevy 250.00 "
That is a deal I want to find LOL

I thought the 6.0 had individual coils like my 2000 5.3l did Maybe he put in an LT1?

My 200 5.3l


His engine

The 250 dollar price he is quoting was for a used 6.0 that needed to be re-built. It is not hard to find these motors for $1500-2000 which is a bargin for the power and effeciency.

No that is a 6.0 LS1 just like your 5.3. It DOES have coil on cyclinder factory but that guy swapped the ignition over to a megasquirt system.

I've talked with him some and he seems like a nice enough guy, however his install looks like a rats nest and I wouldn't be taking that thing on a long trip.


With half a brain and some time you can have a nice looking install that joins form and function.

[saulgoode]

^ I think he has after market coil packs. This guy is using something called megasquirt, does that handle all your electronics and no need to have a wiring harness made.

Edit: Firstgen covered it

[Hart_Rod]

FirstGen,

What would be a good price on a 6.0/4L80E, computer and harness, MAF, Fuel pump module, Electric gas pedal, crossover pipe with O2 sensors. It has "3" miles on it?

Rob

[68LSS1]

Megasquirt is a aftermarket do it yourself fuel injection controller. It replaces the stock ECU, think Accell Gen 7, Big Stuff III, or F.A.S.T. but you build it youself. As far as the coil packs a lot of people move them to clean up the engine a bit. I love LS1's but I'd be the first to admit they are not the prettiest thing always. You can mount the coil packs remotely and run plug wires to them (looks like he mounted them on his firewall). Also as of yet there isn't any aftermarket coils for LS1's. A lot of guys run the truck coils as they are suppose to be a little hotter. Here's a little example of a '99 SS and you may recognize the valve covers as they are the ones I had made and posted recently and my buddy talked me out of them:
As you can see moving the coils cleans the engine up quite a bit. You can see the plug wires snaking back to the coil packs mounted under the cowl. As far as this engine, it is a bored/stroked 6.0 solid roller iron block that dyno'd 555rwhp/485rwtq (carrying 525to 7500 rpm) in 90+ temp and 90+humidity and this was N/A. The engine was built for nitrous, nitrous times to come.



And Rob I think that's a pretty good deal. Not absolutely great but if I wasn't planning on upgrading (heads, intake, cam, etc) I'd say it's worth it. Look at FirstGen's as nice, clean, stock looking example. Well, wait. Does it come with any accessories/brackets and throttle body? If not, no.

[Hart_Rod]

68LSS1,

Yes, it comes with all accessories/brackets and throttle body. I can get it all for $4300 delivered.

Rob

[Joe67]

Thanks 68Lss1.

It does clean it up a bit. Maybe the gains from the aftermarket coil pack are almost negated by the longer wires though? Just wondering.

Rob - which version of the 6.0l is this? GM made a few ranging in HP from 300 to 345

LQ4 has iron heads & LQ9 has aluminum heads

LQ4 - 300 HP 2500 Pickup trucks
LQ4 - 316 HP Hummer H2
LQ4 - 325 HP GMC Denali trucks
LQ9 - 345 HP Cadillac Escalade series & Silverado SS as well as a limited run of Ext Cab Silverado 2wd pickups in a few states around the US.

Regarding price, I think $4,300 for a complete LQ4 maybe a bit high, depending on how far they are shipping it to you for that price. Here is a great deal in Michigan - LINK
I have seen other complete packages sell for $3K or less before shipping

I would say a steal price would be 3000-3500. More realistically you will spend around 4000-5000 for everything with so few miles on it. Pretty much getting a crate motor/tranny + all the other stuff like assessories which adds up QUICK if you are trying to buy it seperatly.

If it were me, I would steer away from the electronic TB/gas pedal. You could sell the TB and pedal together and go to a regular cable driven F-body TB.

All this information is good however the LQ4 and LQ9 are identical motors less the pistons. The heads are the same (317 castings). For some reason alot of the published books have this information incorrect. The only 6.0 that had iron heads was the pre- 2001 motors. The actual difference in the LQ4 and LQ9 is the LQ9 has a true flat top piston (hyper) and the LQ4 has a small dish (also hyper). EVERYTHING else is the same. The books even list different head numbers but this is a phantom head as I have yet to see one. Basically if you get an LQ4, shave the heads a little and you have a LQ9 - or leave it and run a blower! LQ4 = 9.4:1 CR and LQ9 = 10.2:1

Brain is correct, however I wouldn't put it up there with the big name stand alones. It's more of a poor mans FI system. The big reason people go to a megasquirt system is to take advantage of the 2 bar MAP system in forced induction. The factory LS1 computer can only read so much before the MAF is maxed out. The smart guys use megasquirt as a piggy back system to control air/fuel instead of a full stand alone aif/fuel/spark.
BTW - MSD does make an LS1 coil but I really wouldn't see the point at $75 dollars each.

[lilred67]

take a look at this web site www.hotrodlane.cc they specialize in installing new model motors in old vehicles.they have a article in classic truck mag.,(july'05) installing an ls1 engine in a '73-'87 model chevy truck.

I didn't consider the engine he is referring to is basically new, not used

I was unaware current LQ4 motors have aluminum heads, that is a good thing.

Here is a link to the current Vortec motor specs

I agree with FirstGen (almost) and I didn't mean to put the Megasquirt comparable to the others because it's not even close. Note on the engine above is still uses a stock ECu so if you have access to a good tuner you can push them pretty far. As far as the throttle by wire I'd use it. One question though. If he doesn't use it, won't he have to get another ECU or flash that ECU with a model year program that had the cable driven throttle body instead of electronic? I didn't know MSD had come out with a coil but at $75 per I think I'll pass. And as far as the thread for Street & Performance that lilred67 provided, they have some good stuff but a lot of it is a lttle on the high side (price wise). And Rob, like was mentioned, not a super deal but not bad either. I would compare it to buying a crate engine also. Get it and one start saving for one of the new 6L80E's. Throw the Shrifter on there and drive the crap out of it..... Sorry, I get carried away.
