That's my point, AO. I would assume "true mileage known" would assume the miles of the engine and chassis, and all other bits to be relative, within reason.
Otherwise, it's TMU. Agreed?
If someone lists FS a car with 200K on the odo, with a recently rebuilt motor having <5K... does the car have 200K or 5K?

I mean that in order to swap a SBC for a Porsche engine, and back, you are going to have pull all sorts of electronics, hoses, etc from the car then replace them. You could do a perfect job, but it will never be quite right, and never quite the same as the original install done at the factory. Swapping a motor from another manufacturer is not the same as rebuilding a motor and replacing it .

Other times the story can make the car. I would love to own a DBR1 Aston Martin that had the snot beat out of it at Lemans in 1959 and was co-driven by Carroll Shelby.

After plenty of research, I do agree with what Jon B's had to say. The modern day LS376/480 engine from GM. Specs: 480hp, (dyno's at more like 500), EFI, aluminum block & heads, 6 bolt mains, nodular crank, high perf connecting rods, 10.7:1 pistons, roller rocker high perf camshaft, high flowing rectangular port heads and lightweight hollow stem valves. That should incenerate those rear skins ! So thats +155 hp over the stock setup and a 160lb weight reduction. Passes all states emmisions laws, it's brand new with 0 miles, and comes with a 36/100,000 mile warranty. I do like those numbers. T

If you look really hard I'm pretty sure you can find those engines with fuel injection.

Google: "LS3 Jay Leno". Jay Leno's garage has a video explaining the emissions, etc of this motor alongside a GM rep much better than I can. T

Tony, you've not made assumptions about GTS engine endplay measurement, right? You know its within spec? It would be the second item i'd tout, just under mileage, in a for sale listing.
(The reason of asking is that some have failed very early on the mileage meter).

Not that far yet, and did not know about that. I'll just put that on the list of "Things to do before pulling the trigger". You can also offer some insight on end play measurement right here on this thread for all to see, Thanks for the tip. T

LS, Thanks for those links. From what I have gathered so far is basically this. We really don't want to put in much more than 500hp into these cars if the drivetrain is going to remain basically stock, or your going to start breaking things. It's usually the weakest link that goes and it sounds like the thrust bearing & flex plate might be the culprits. I really like it a whole bunch when things stay together. Roger has mentioned to me that most of the performance nuts who are installing superchargers, turbo's, stroker motor's, etc are doing it the the automatic cars because they can take the extra juice. I had the same transmission (I think) in our Mercedes/Porsche E-600 Renntech that was double duty on the track & street and was producing approx 550 hp at the crank. The transmission & rest of the drivetrain held up just fine, and believe me, that car was not did not pampered. T

Naw, its the stock engine that fails internally at stock hp due to a porsche application design flaw.
Its the achilles heal of the 32V engine / auto trans car, taking some down in the 40K mile range terminally. #1 PPI item: release tension and record endplay. It will be important to your sale to demonstrate that the engine is sound on this issue. In fact, its the main reason somebody would want to buy a replacement GTS engine.
Love that 500 Benz.

It's usually the weakest link that goes and it sounds like the thrust bearing and flex plate might be the culprits. Thats one of the reasons I want to go with the LS3 480 hp motor vs the LS3 515hp motor. I really like it a whole bunch when things stay together.
