I do apologize for turning over every stone, does seem like I'm arguing a little. I simply felt some were thinking "these people are fixing to get screwed" (& I appreciate all of your comments) I felt it nescessary to vouch for the seller and the og owner so noboby got stuck there. Just got the best news!!!
hey there, my #1, my sailor son.... Your inheritance just expanded!
just heard back from Mr. Kettman. BINGO!
"Ms. Conner & Mr. Bennet,
Yes, the numbers on that block are the serial numbers, it shows that this was the 6th batch machined in Oct, 2003, block #16, not sure about the "P".
This is actually a "C5R" block, pn 12480030, not an "LS6" block. These blocks were originally designed for our Corvette C5R racing program for the Corvettes that race in the ALMS and at LeMans.
They come with a 4.125" bore and are often made into 427 cubic inch engines w/a 4.000" stroke.
Here's some info: https://store.gmperformanceparts.com...umber=12480030
If you poke around on this website, there's also a downloadable catalog or a way to order a paper copy.
Best regards,
Jeff ~ Parts
Thanks to everyone who stepped up with their opinions & expecially to those who posted comparison pics. I think I'm putting this in the civic. LOL

Just as an update for everyone.... The block checks out kosher. It's a true C5R block.
Now, the important question- What would Y'ALL pay for this thing? I don't want my mom to get screwed over here. Also, she's freaking out about whether or not it should be carbed or EFI. I hate dicking with carbs and grew up messing with Hondata and Megasquirt, so I'm biased. What would be a good direction for this motor?

Does the seller know what they have?

Bolt an Edelbrock Proflo xt on top of it with a 90mm tb, 42-60lb injectors, 2000+ computer and harness, then get Hptuners......if your familiar with hondata you can switch over to Hptuners very quick and easy.

The block is expensive, but I'm not sure it's worth the price that was paid for it. For the amount that was spent, you could get a tall deck RHS block, or a warkawk block etc. I think at the time that the C5R's would get the most value was prior to the ls2/ls7 blocks being available. I'm not sure there is a big market for the C5R block to be honest.
For the shortblock as it stands, I'd guess you're looking at a market value of between 5-6K. Maybe more to the right person, who knows.

son, look at these 2 links and well me if it's what i need. connecting edelbrock 2908 to the MSD coil packs.. I'm stuck, & MSD/Edelbrock tech lines both heard my fifi voice and couldn't take me serious enough to direct me, but one man who caught 'mama's wrath' stepped up when I called back @ MSD. I THINK this was what he was talking about.

Really, it's a historical thing more than anything at this point. Very cool, no doubt.

That was my point. Back before the gen 4 motors showed up, the only option for a factory, large bore block was the C5R. Granted, it's a badass block, but today, you can get an ls2 to do everything a C5R can do, block wise. Heads are a different story, but then again, there are so many aftermarket castings available as well.

I'd rather spend a lot less money on an engine that will last exactly as long, be just as reliable, and make WAY more power than that engine. Resleeved LS1 or LS2 block, 441ci, LS7 top end. 600+ RWHP pump gas engine.

I guess it would be cool just to be able to say you have a C5R block.....because thats all it is, the block. Blocks are responsible for making ZERO power, its everything else.

I disagree here. The C5R block has features that makes it a stronger block. In addition it has AFR heads, a Forged crank/rods/pistons/ its over 400CI. I would say its a bargain in the $4K-$6K arena. You can't build that for less with those parts. Hell you would have a hard time getting an LS3 for that.
Whatever features it has that makes it a tad stronger than other blocks......makes absolutely no difference at all because its a low power engine. If it was a max effort 850 HP race gas solid roller build....then it would matter. Thats why its such a waste of money....its a low power build.
AFR heads.....nothing special there at all. Ported LS7's, MAST or All-Pro's, make them look silly.
And again, like I mentioned.....blocks make ZERO power, its the all the other stuff that makes the power.

Thought they were asking $10,000......if they can get it for say $5,000...that would be awesome.

Your right a block makes no power, BUT has the potential to support alot more beatings than a factory GM LS block. You need to consider you can not compare this block to any LS1/LS2/LS3/LS6/LS7. It has a 4.125" bore, billet caps, etc. Its a superior block you just can't compare to any other aluminum LS Block.
Around $5K is what I would pay considering you need more parts to get it going.
