66 2.0 engine valuation

[Igofastr]

Short story; I have a '66 2.0 (#9037xx) that I bought maybe 5 years ago. It had been rebuilt (supposedly by a P shop, but have no documentation). It was used briefly as a sand rail motor, but was pulled because it lacked the torque the owner wanted. He said it sounded great. I saw the sand rail, and it was a very nice piece of kit.

The motor looks complete and original, except that it has webers in place of the original solexes. Per the owner, the P/C are probably 2.2 units, with an early S cam. Headers are present, but dinged up a bit. I haven't done a leak down or compression check, but since its been sitting awhile (always inside), I'm not sure what I would believe. I'm considering trying to start it, it turns by hand.

SO....

I'm seeing a fairly wide distribution of asking prices for these early ally motors, up to about $30K. I realize that earlier is more valuable. What is a reasonable expectation? I'm looking to fund a different automotive project, but don't have to sell if I don't want to. However, I may never actually use this particular motor.

Any informed comments are welcome.

Wow. 80 something views, and not a single comment.

This must be the least opinionated car group I've ever belonged to.

Ron, hard to say without knowing how original is it and no documentation. Valve covers original?
what is the date on the engine? Also being a 66 knocks it down a little over 65's. I would guess $15k-$22k as a rough estimate.

[Yorkie]

I would say a little lower at between $12k and $15k But without pics docs and history it's hard to value. Most would regard it as a core. If you can unite it with the original car ( see EarlyS registry) then it will hit the upper end otherwise it's going to power a non-numbers matching early car and those guys are serious about originality. The numbers do not match on my S so it's value is hammered

[Matt Monson]

I think how bastardized it is puts it about half of Fubawu's number unless the Webers are IDS 911S carbs. If the cams were real S cams and not reground S spec cams it would help. But that requires some disassmbly to verify, as would P&Cs.

If it was built on original factory parts to that spec, then Fubawu's number is legitimate. But it's an unknown core with a story about what inside and no receipts or build sheet. Its a crap shoot for a buyer so it's value really comes down to what the serial number is worth, which I think is $7-10K. maybe 25% more than that if the original owner is looking for it and you post the actual number.

[Fubawu]

Guys I just don't see 66's listed in the 10k range. The fact
there is no documentation makes it less valuable. But if numbers
come back strong. What's the fear in using instead of treating it as a core?
The carbs alone are $2500 min and as Matt said IDS S will add to that!

Let's be honest what do you get for 10k, hell complete mid year engines are going
for 4-7k

[Igofastr]

Guys,

Appreciate the comments.

When I am actually home during daylight, I'll drag it out for some pictures. Not being an expert on these, I believe it to be outwardly original...valve covers etc are there. It looks pretty good, no evidence of leaks, etc. Of course, the fan shroud was painted, but the only other obvious deviation (to me, anyway) is the webers (and braided lines that were plumbed to an external sump tank, but these would be replaced anyway).

Personally, I'd prefer the 2.2 P/Cs, more power and they look the same.

I'll see if I can't add some pics this weekend. Maybe do a leakdown just for yucks.

If I get a chance, I'll see what else I can find out about the motor/carbs tonight.

The case number is 903781, which I think should put the build date as late 65 or early 66, for the 66 model year. I don't have my books with me, but that's what I'd assume.

[Fubawu]

just for reference, not a 66 but this case sold in 40 mins at $3k

Fubawu,

Thanks...damaged web and spun bearings to boot.

BTW, my engine's carbs are Italian Webers 40 IDA 3c.

[Matt Monson]

I could be wrong, and the simplest way to find out is to actually list it for sale. It's generally easier to drop a price than raise it.

[Igofastr]

Matt,

I'm sure you're right. But since I'm not sure I want to sell it, I don't want to frustrate potential buyers by just trolling for offers.

[Igofastr]

When it stops raining...apparently not for a while, I'll drag it out and check casting dates where I can and do a leakdown. I'll post pictures and the results. Then we'll all have a better idea where it stands.

Totally understand. I'm actually surprised if you aren't getting pm offers.

[Igofastr]

Matt,

I have. Just not ready to bite.

Thanks.

Matt, I have a 65 built, 66 production with correct carbs and shroud. I'm thinking $18,500 is a pretty fair number. Hope that helps.

That sounds close to market in my opinion pending condition.

Correct carb you mean Solex .Complette solex set up is 8-10k alone if you find one.A mid 66 with weber the carb one year only they have S stamp on carb. 7-10k range for 66 unknow engine and parts

[Igofastr]

Guys,

Appreciate the input.

I WILL post more info. Unfortunately, I've either been working, or its been raining. To do a leakdown and take decent photos, I have to move another car that I am loath to expose to the rain. Unfortunately, its supposed to start raining again on Friday.

I'll keep my fingers crossed.

I think it was early 66 that the switch between Solex and Weber took place?

[pors1968]

They start to used Weber feb 66 and production model 911 is 01 08 65 to 30 07 66 febuary 66 is mid year prodution
