Hei dist.

Milodon oil pan

Runs great only 6,000 miles since rebuild

Looking for current market value, I may be changing to a LS based engine?

Would love to find the original 69 Corvette that it came from. Not sure if it was a coupe or convertible for the vin search.

Thanks in advance, Jeff

Nothing shows up on the C3 registry.

Where are you located?

jwcarguy

Yeah, I checked on the registry also

I am in Las Vegas

There are two around here (Wisconsin) going for $4800-$5500. One is built up the other is just a short block that's been machined. I believe one says it is from '67.

I know it's not the best source of market information, but that's what they're trying to get around here.

and good luck!

jwcarguy

Thanks for that info.
I would like to see it go to a car that "needs it", rather than some old drag car motor, if you know what I mean?

thanks, Jeff

jwcarguy

May even trade out for a nice LS engine and T56 setup??

jwcarguy

no other input?

jwcarguy

Any current input?

Thanks in advance

The thing is that most of us probably only see ads of what people are asking for these items, without the knowledge of what it sold for [outside of an ebay buy it now].

That 512 block always seems to have an asking price of above $1000 by itsself, so I would think a running piece made out of one should get a few bucks.

Originality wise, we know those 049s didnt come with it, nor did any of the other components (outside of the crank I assume), so its possible that the real value may be closer to that of a "drag motor". \

To a person whom is looking for originality, this motor may not offer much [unless you are the lucky person with the matching VIN]. Keep in mind though, that even if you do have receipts for every part and machine work, it is now a USED motor. You may know the history of the engine, but dont be surprised if every buyer doesnt take your word regarding mileage.

Could it be worth $4500? Possibly to the right buyer. I'd be willing to bet most offers will come in around $3200..from there its up to you to feel things out. Rarity is on your side though

If you find the car it originally came from, it could be worth a small fortune. If not, it's worth what any other used motor is worth, which to most people is very little.

jwcarguy

Dave,

well said!
I agree with you on the "used" engine aspect of it.
I have been auto parts for years now, and have had to deal with that guy that unfortunately is standing with a fist full of receipts, adding them up to calculation his asking price!
I understand that it is "used" and that the top end is upgraded, compared to being in stock form
I was hoping to get around the $3800-$4000 mark, when it is posted up for sale, I am sure that some people will "lowball", but that is why they refer to it as a "asking price"

Thank you very much for your input!

Jeff

jwcarguy

Yes, that would be nice to find the original car for it!
But at the end of the day, it still is a true 69' 427 (rather than a pieced together destroked 454) so I feel that there is still a lot of value to it.

When I was still living in NY, I had a few guys that wanted just the dated 512 block for 69 Camaro COPO /tribute cars, I didn't want to sell then.
Thanks,
Jeff

It only has value to someone looking for a period correct casting, and even then it won't be number matching. To everyone else, why would they care if it's a destroked 454. Actually they would probably prefer a 454.

These people are not very common. If you find one, consider yourself lucky.

i wouldn't pay anywhere near 3200$ for a used motor. especially one with the hypo parts.. all that says is that it has been rev'ed into the stratoshere and will need to be rebuilt and is probably ready to let go. .030 means probably rebuilt more than once...

check the stroke.. it may be a 454.

asking price and selling price are 2 entirely different things.

Big Block Dave

Joe,
Crank 6223 is 427 or 396, so he's got a 427 for sure. You and I arent far away with the thought of actually paying $3200 for a used motor, but people will...for example here is a story of a motor I let slip through my fingers...

A close friend of mine had been running a 468 in his Nova since 2004, and for a brief spell had a procharger on it. He is doing an LS swap, and the motor was first offered to me (minus procharger). I could have had the motor for $3000, which would have included GM forged crank, rods, forged pistons, 990 heads 2.19s, solid cam, scattershield, clutch, from the milodon pan to the victor jr.

My friend is EXTREMELY meticulous, and I knew it ran well, but I didnt feel the need to spend money on this since I do have a running # matching 454 in my car. Motor sat on craigslist for a few weeks, and ended up getting sold for $3300. That day I sorta regretted letting it slip away.

Another friend recently sold a 406 with AFR heads for $3500. The key here is this...if the motor is running and in a car, people will buy it, but yes they are used motors, and there are some largely varying opinions on what a used motor is worth.

I tend to undervalue most things because Im always looking for a deal, and vice versa, when I want to sell something I dont want to sit with it for too long. Other people will hold out for every last penny...Id rather sell to a reasonable buyer who has cash now.

As for the poster...plug that motor into a car and it will sell. Sitting on a stand puts you at a big disadvantage, but people still buy them that way.

Too bad you dont still live in NY!

jwcarguy

Thanks for all opinions, some I agree with and some I don't

Update: just sold the long block only to a guy with a 69' that needed that casting # and date
Sale price: $3,000
Still have to sell of the intake carb air cleaner oil pan front accessories and headers

Thanks Jeff

You done good.

Big Block Dave

I agree! Well done

Wonder if it will be restamped?

bashcraft

Of course it will. No one is going to pay that much money for a date correct block and not make it numbers matching.
