Question re LS7 replacement. Will dealer credit for LS3 engine?

And there are still plenty of options to go way over 500 hp with an LS3 if need be, that would probably still cost less than the $15k+ for an LS7 crate motor plus installation. The OP already said all he plans on is the motor and a cam. IMO unless you blew your LS3 up drag racing and need a complete new motor anyway it this is a colossal waste of money.

To answer the OP, they would not credit you anything IMO because it is still a used motor (even with no miles) because its a take off from a car. It is serialed to your car and so forth. Plus they could not sell it for full price, and dealers do not use or sell used parts (they will however use remanufactured parts if thats the only way to get them). That said you could likely ebay it for almost as much as one sells for brand new from GM so you really wouldn't take that much of a hit. That said as I mentioned above, you can go way faster for way less money just modding what is in there already....

A lot of Valid points and I must say after some consideration, I will just get a 2SS and mod the Vette first then maybe a couple of Twins later. By then there should be some nice packages out from LPE and others. Thanks for the info all.

Engine already built and dynoed,just waiting for the car to arrive , yes LPE does all my engine work.

You should be able to run a twin turbo kit on stock internals with low boost, and make alot more power than most poeple need. APS has been making TT kits for corvettes for some time now, and they put down over 600whp. This would be alot cheaper than trying to swap out an LS7. Plus you'll be making alot more power.

I have an APS Twin turbo setup on my GTO. Its only been on there for 4000 miles or so, but i dont see the motor lasting too long. I have a very safe tune and still put out 565 rwhp. lol. I just don't see it lasting more than 10k miles or so. Of course, I would love it if it did.

I've been out of the GM scene for some time now. Why do you think your motor will only last 10K miles? Also I'm sure you can get a bottom end built long block for well under 10K. I bet your car must be a blast to drive.

I agree what would indicate to you that your motor won't last much more? Ticking noises?? (which are common in LS series motors) , blowby? ????

8 lbs of boost on a stock bottom end?

8 lbs of boost on an aluminum block motor with 6 bolts mains.... Thats the stock bottom end. Is there anything to indicate you are doing any damage? If you look at the bottom end of factory boosted cars (Syclone, TTA, GN), they were no beefier, in fact even less, running more boost (stock was 17lbs). I see no reason unless you are consistently drag racing the car or just straight out beating the piss out of it that it should eat up that bottom end.

I might be able to answer that. Because nobody else has, and he'll be rare and original.

Sort of like people who mod FWD Grandprixs and swap motors into old commuter cars. Because nobody else does it, and it's original.

idk...

you could also look at lingenfelter built ls3 it has 550hp and 550 tq and it's cheaper than a ls7 and you might be able to sale them your stock ls3 to help even things out just my 2 cents

I'm not out to discourage anyone. Hell—I'll be slapping all sorts of stuff on my SS. I just wondered why it would be desirable to make an all-track beast out of a car so heavy. With the same resources, you could build a lighter car to go even faster.
