Assume you do not have warranty..... and the engine croaks. What would be the total out of pocket expenses to replace the engine?

HurstSRT

There are a few used complete motors on ebay. Most low miles. One even has under 10 miles and comes with the transmission. This one is $15,000. The others run between $10,000 and $12,000. I would assume going this route would be cheaper and easier because they are complete with sensors and harnesses. I don't know how much a new engine from GM would be and I don't know if they are long blocks, short blocks or complete engines. Probably much more money.

I would assume labor would be at least 10-12 hours under warranty. I would bet double under customer paying the bill.

The WHOLE engine usually doesn't croak so replacing the part that breaks can be done cheaper I am sure. Especially since you should upgrade whatever broke and maybe stuff around it at the same time.

I'm asking for a whole engine replacement, to bound the costs of a different problem. THINK, buying someone's supercharged Z51.. There's no warranty, sure it has more power, but its also more likely to have a failure. What are the bounds on the costs of replacing the issues caused by that failure. ---Asking what are the costs to replace an engine, is a pretty good bound on that problem.

A complete LT1 crate engine is $11,644 MSRP. You could likely get it a bit cheaper from a forum vendor. I'd contact a vendor like Trunk Monkey to see if long blocks are available as that is likely to be much cheaper.

I would guess labor on an R&R would be ~$5,000k.

rebuild not replace. GM wants a fortune for the LTx. You can rebuild it for 3-5 grand (as long as there's not a hole in the block of course).

ilivas

You could flat out buy a fully forged shortblock for less than a crate motor. Even with labor, it will likely come out cheaper.

jayjordon

Agreed

davepl

Yes and no. It's certainly an upper bound, but may not be a good reference point for decision making because all but the MOST catastrophic failures can be fixed with a rebuild, not replacement, which is far cheaper.

Clearly if you puke a rod out the side of the block, you're going to be looking at a replacement. But if the supercharger causes detonation and breaks a ring land, the block will survive usually. Cranks can be turned, heads replaced, all of that sort of thing.

I don't think you're using the word bounds correctly.

Higgs Boson

he's ok with it.

Figure $12K for the new Z51 Dry Sump Engine and a week of labor plus other materials such as coolant, oil, miscellaneous parts maybe an engine mount or two.

The advantage of replacing an engine Vs rebuilding it is you get a warranty from GM. GM doesn't seem to rebuild engines as it is lower cost for them to just replace the engine Vs rebuild. With a rebuilt engine they really don't know what they have while they have a long history with complete engines coming off the line.

I suspect if you go with a highly reputable shop that rebuilds a lot of engines and doesn't take short cuts you may be able to knock $5K off the cost of the crate engine but the warranty won't be the same.

That $17K amount is close to another person who posted that it was $16,000 installed for a brand new LT1.

BTW, we have seen between $28K-$30K installed pricing on a brand new LT4.

My LT1 dropped a valve and cracked a head. Dealer quoted me $14K Canadian to replace the motor. (Not under warranty) That price likely would've gone higher had I agreed to do the work. I did not and sent it to LPE to be rebuilt, stroked and made bulletproof.

Dcasole

Funny ... my LT1 dropped a valve also and it was $14,000.00 plus American. But it was covered under warranty

What I find funny is I am hearing more and more about LT1 dropping valves ....

If it makes you feel better... it ended up costing me $30K after building the motor up at Lingengfelter and other supporting upgrades haha.

Wow ......
