That sounds about right.. If the motor was OK (and just needed a rebuild) might be worth keeping the stock block due to matching numbers. Otherwise I would drop a LS3 505 HP GM Performance engine in it and call it a day!

Would cost about 11K for the LS3 motor (including installation and tuning), so you would be looking at 23K total for the car.provided the trans and rear axle were still in good shape.

Shame this happened to a 9K Z06. Would have been worth around 26-27 unmolested.

 

you have no clue what you're posting

at all

zero

i mean you don't even know the hp output of an ls3 and you're trying to give advice on labor costs you also know nothing about?

you're seriously trying to argue a popped motor devalues the car by 15 grand?

the engine is 6500, install is 2k MAX and tuning is $350, that's 8850 and the buyer will recover 1000-2000 by selling what's good on the old ls6

if you argue it's worth 12, that means 12+8850-1500 = 19,350 for a 9k mile chassis with a brand new ls3, add in an ls7 clutch while we're at it with an aluminum flywheel just to make it 20k

that would be the best deal i have ever seen for a car that mint

 

Hmm, did not realize that a GM PERFORMANCE ENGINE was a STOCK ENGINE! But yeah, guess you know more than GM!

Look again and I SPEFICICALLY STATED A GM PERFORMANCE ENGINE, not a stock 430 HP LS-3!!

Why would I pay $7,730.00 for a stock LS3 430 HP crate motor, when I can get a 525 LS-3 performance engine for $7,831.00? Both have 2 year warranty.

I am going to provide you with the link, so you can educate yourself!

Yes, I am suggesting that a non running C5 Z06 devalues the car considerably!

In your assumption, you are convinced that the motor is all that has been damaged. How was the engine damaged? No oil in motor, overheating, dropped valve, or overrevving and clutch dump?

If the latter, then the transmission could have been damaged, along with the differential (if overreved engine and clutch dump), etc.

In addition, he is not fixing it, selling AS IT!! If he wanted to fix it first, of course he can get a lot more out of it, PROVIDED IT LOOKS AND DRIVES LIKE A 9K car as well.

If you want to buy a non running C5 Corvette for 20K, go for it! I do not know many people who woud do that, however. Certainly not I.

Of course if he wanted to FIX IT and then SELL IT, then of course he could get more for it. However, with a broken drivetrain, just too many unknowns to sell at a premium price. Best thing for him to do would be to fix it, then sell it. But that is not what the OP stated he wanted to do.

 

Wake up America! I blows my mind that people think a car worth 25K+ is only worth 10 to 12K because it needs an engine or an engine repair.

 

I mostly agree, but you can't just drop an LS3 into a C5. There are additional costs that you are overlooking, but they certainly don't add up to thousands. I'm going through that right now with an L92 swap.

 

So what do you think it's worth?

 

I think its worth finding the time to fix it. I have a 2005 6.0l short block out of a 2005 base corvette that only has 5k miles on it and I also have a 6.2 out of a 2013 Escalade. This thing may only have a minor repair needed--I have committed one of my techs here at the shop to repair it in the evening.

 

I completely agree with you; especially if there were no other problems with the car. The 6.2 escalade engine (L92) is what I'm doing now. It requires some "stuff" (Obama's term) to make it work. If you're looking for quick and easy so as to turn around and sell it, I'd stick with an LS6.

The 2013 will be even worse because it is actually an L94 and you'll have to convert it from active fuel management.

 

It blows my mind, you think a car that could be f***** is worth 25K, when it could be only worth 10 to 12K..


Glad you have decided to fix it, come back and tell us what the tech finds..

 

you need to drive your car into a cliff, save me from reading your ridiculous posts

 

totally

and we still aren't completely sure what's wrong with this 9k mile car. it's just a bit off the charts to start talking 12k on a car like that just because at worst it's a popped motor

 

You are absolutely correct. wiring harnesses adapters you will need for MAP sensor, Cam sensor, and knock sensors. May have to use another cam gear as well. That is why I priced motor and installation at around 11K.

Say $8, 000.00 with taxes and shipping for LS3 525 HP crate engine.

Wiring harness adapters: $ 300.00 all (including taxes and shipping)

Edlebrock 2 piece Timing Cover: $180.00 (optional but makes it easier to replace cam, if needed).

Cam Gear: $ 30.00

Total Parts (approx): $8, 510.00

Installation: $ 2,000.00

Dyno Tune: $ 500.00

Total: $11,10.00

I didn't even look this up before and said about 11K. Was pretty darn close!

 

You need to get a clue.

I suggest you read how many agree with me rather than you BUM!! But hey I am sure the owner will let it go to you for 20K plus, since you think it is worth it as it sits!

 

Racebum kills it on this forum, I rarely post because when I do a search 75% of my questions are answered by him with a great explanation. All i have to say.

 

You can find a low mile used LS3 for half the price and installation shouldnt be more than $1000... At least thats what it cost me to drop in my LS7.

My guess.. $6-7K to drop in a used LS3.

 

Of course you could. Could also drop a used LS6 or LS7 in it.

Of course used LS3 or LS6 would not be over 500 HP without some serious work.

Think the OP has decided to fix it. Good move. Will get a much better selling price.
