The car looks clean in the pictures with only has 29K miles and after reading your prior postings I see the first owner installed the aftermarket engine when the car only had 8,000 miles and it's been to the track a few times... 1/4 mile at 11.70 130.2 mph on street tires. So the original DTE 427 has only 21K miles.... what was the reason it needed a recent rebuild 6,000 miles ago?
What engine block was used, GM didn't offer an LS7 in 2004?
The original engine builder "clutch dust" ....said, this is what is in your car...
The engine is actually a 447ci. LS3 (4.155" x 4.125") using ERL cylinder sleeved block and a bunch of other expensive, go-fast, HD racing parts
Do you know what compression the engine is currently at?
Also, what brand of internal parts were used (crank/rods/pistons)?
This would be an interesting car for a twin turbo build.

Sometime in the late 2000's, the original LS6 engine was pulled and secured/sealed onto a pallet to be kept w/ the car after other future modifications/upgrades were completed, as were most of the original factory parts that came off the car during the upgrade process. An LS3 cylinder block was chosen and Darton-sleeved to accommodate the 427, using Callies cranks/rods, Mahle, Comp Cams, ARP throughout, Cometic, AFR, etc. etc. etc. The LS3/427 combination made excellent power. After a few thousand miles, the owner thought it may be using more oil than it should, so it was sent back to DTE and inspected thoroughly. No issues were found after mechanical testing was performed that would warrant disassembly, so the owner figured, "since the car was there", why can't the engine be made "bigger" before it comes back home...
So, a new LS7 cylinder block was purchased, sent to ERL and they re-sleeved to accommodate the 447 cid. w/ the stroker crank to match. The short block was then built by ERL using all the same HD go-fast goodies previously mentioned, then it was sent back to DTE to be finished-built, installed, tested and re-calibrated. A slightly bigger cam was selected, where this combination made even MORE N/A power! The power output curve was just plain stupid-crazy on a mild 91 octane pump gas tune at 11.6:1 compression! The car started easy, drove smooth, (comparatively) is brutally fast and shakes the bumpers at the stop lights. Nice, clean, fast, well-built and maintained high performance Corvette.
Brief synopsis is about all I can remember after 12+ years and I'm sure I'm forgetting a few things... Good luck w/ the sale if you haven't already and the new owner won't be disappointed.
Clutch Dust out for another decade....
