Small Block Engine Casting Numbers

I am trying to confirm a motor, it is a small block Chevy 350, the casting number is 10066086, I cannot find it in any of the books or on-line sites.

Can anyone give me some help on identifying, year, age of this block?

 

Is it possible that the 8 is a 3? I ask because if you search Mor tec they have a listing for 10066036.
This is what it reads.

10066036...350...........2 or 4...Target Master/Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"




Thats coppied right off thier site.

Could be a 3, hard to read it, and the guy said it was a crate motor, so I guess that all fits into the story

 

sorry to hijack your post..but is there any other sites other than mortec?...mortec told me my motor was a 1968- 327 small journal...but i kinda need to know what the motor came out of....

 

The suffix code on the front passenger pad of the block will tell you that. There should be a sequence of number's and letter stamped there, and the last letters will tell you what the general application was for your motor..
There could be one letter up to three..

Check out this site. There is a listing of suffix codes that you *should* be able to run through to get an idea of what your's came from.

Hi Guys,

Can any one confirm what ive got
GM 10066036 on the block
33426651 on the crank
462624 on the head
1M0403 7H04 stamped on front of block
H04 12587265 on a sticker serial number stuck on the sump
I open the sump and is a 4 bolt all cast pistons had a B stamped on it???
As i got shafted on ebay saying its was a blown motor complete n new which it is
I contacted the speed shop that the seller told me it was from and wasnt.
So just looking at what i got if anyone knows,
Will build it and put 6-71 blower ontop see if it goes bang.

Positive comments please
Cheers

 

What do you mean by "positive comments please" ... what have you heard about this place??

Is there a suffix code on the block deck, right front???

 

hecho en mexico?

Sounds like a GM crate motor, probably not one of the better ones, sorry

 

I just wanted to confirm the bum deal i got for the package, and ive got to suck it up
i will put the motor together and if the bottom end lets go so be it.
