LQ4 value

[-83MONTESS-]

I have a possible line on a LQ4 6.0L with just a tad over 300k miles. The head gaskets are done and my buddy is thinking about just replacing the engine instead of rebuilding this one. What would be a fair price for just the engine without the wiring harness? I'm new to these LS engines but I really want to build a boosted 6.0L in the future.

If it comes with the complete accessory drive and starter, I would say $500 tops. That is a lot of miles.

In my opinion unless he is willing to give it away you would be better off buying a crate engine. At 300k that thing has significant wear

I know that it has lot of miles on it but I'm not too worried about that because when I do eventually get around to messing with it it will get a total rebuild. I know he always maintained it and he parked it as soon as he saw coolant in the oil. It ran like a top and I can verify that. I would just love to grab this and set it under the bench for a few years until I get the funds to build what I want.

$300-$400 tops. I don't know how much you're wanting to build it but you can get new 6.0 blocks for like $700 and build from there.

300k miles is ridiculously high even for a 6.0 litre. I'd say it's 'worthless' because it's a gamble meaning: like $250 - 300 and that's it. Because it's huge, you're basically doing him a favor taking a chance on this engine to pay him anything more than scrap value b/c just like any gamble you could lose on this one and I'm assuming you're moving it yourself.

I know the 6.0 is worth a tiny bit more than the 5.3 but i paid $460 for mine minus the harness and starter and that was only 128,000 mile motor that was super clean on the inside when i pulled it apart.
Now i understand the LS is a strong reliable motor that will go for a LONG time but 300,000 even if you are rebuilding it i wouldn't give a dime more than scrap value cuz thats alot of miles! I would do $250 tops just because there is parts you can use

150 bucks. Throw some rings and bearings in it. Spend the money getting the heads rebuilt. Watch your buddy wonder 'why the hell did I get rid of that engine.' The iron LS blocks are very resilient.

Ok im gonna start at $250. Lets say I get it and do a total twin turbo build, is the factory harness needed or is that something I can buy aftermarket or make cheaper? Im new to these engines if you cant tell :lol:

There is a guy on LS1Tech.com that bought a high mileage 6.0 liter like this. It was running but made a strange noise that he thought was caused by the lifters. After taking it apart he found that one of the cylinders was egg shaped at the top and allowed for .100" of piston movement. Just sayin.......you might be pissing in the wind on this one.

You can buy a harness and ECM set up ready to go for an engine for North of $1000 or you can buy a factory harness from a salvage yard and modify it yourself. Either way, you will likely need to modify wire length and routing so brush up on your electrical skills. LS1Tech.com has everything you need. You should spend some time there reading. Youtube also has some vids (check out the link below)
