Just at the end of an 18month extensive restoration of My 67 SS 350 My motor was stolen (along with a bunch of others) from the machine shop doing the restoration-rebuild on it.
I found another motor that the seller claims is from Another SS350
The numbers are as follows
Block          3858174      2 bolt mains    large journal crank  cast date dec 66
Heads         3817782      camel hump cast same as motor
intake         3905393      cast same as motor

Any way to tell if this is an authentic 67 SS350 Motor?

The intake looks correct, but I don't recognize the block or heads.
The block should be 3892657 and the heads should be 3890462.

That block (3858174) is a December, 1966 327 block and I can't find any info on the heads (3817782). You positive about that number? I do show a 3817682 as being 61-62 283 heads, but no 3817782.

It will have an authentic Camaro partial VIN on the stamp block with an engine code consistent with a SS350.  See http://www.camaros.org/diffs67.shtml and http://www.camaros.org/numbers.shtml

Thank you for the responses....but I am slightly still confused. Car and parts magazine "Catalog of Chevy V-8 Engine casting numbers" on page 14 shows 3858174 being used for 67 Camaro 350.
Further down the same page it shows 3892657 only used for 327 and ,302. Is this refrence not accurate or dependable. What should I be refering to besides the web?  Motor is supposed to ship next week and I dont want to screw this up..
Thank You

The most definitive list of known block applications is provided by Colvin, and this is what CRG uses as a baseline - Colvin researched back to original Chevrolet factory data - all other lists are frankly suspect.  CRG takes some of Colvin's work a step further for 67-69 Camaro.  In the CRG link header at the top of the forum pages select the 19xx Model ID and scroll down to find the info to ID your model (at least most of the V8 models).

The particular block you mention, 3858174, is primarily known as a 66 block and isn't known to have been applied to 1967 models, but I can't rule out a 67 application.  That the block supposedly has a large journal crank with a Dec 66 date indicates that - if crank is original to the block - that this block would have been in a SS350. However, my statement above stands.  You should still see a 67 Camaro partial VIN on the block stamp along with one of the 67 350 motor codes shown in the CRG link above.  And CRG has yet to see one of these blocks in a documented original Camaro.

Thanks again for all the help and guidance
The complete engine came today and the numbers were as you all said Block 3892657 Partial vin
7N123357 and V0803MS heads were 3890462, intake 3905393. The only thing I'm not sure about is the crank it is not 1182 it's 2690. Colvins book pg.83 the 19th crank down lists 3892690.
Could this be the orig. crank it is def. forged steel and also does that partial vin and other engine number sound correct.
