I am trying to decode a buddys 70 vette which has the following numbers on engine pad
111195930 k06 01 cgc
Any help would be appreciated

The block numbers indicate a 245HP 350CI engine assembled in St. catherines engine plant, Ontario, Canada on the 1st day of June for a full size chevrolet. Could be a police/taxi or other H.D. fleet application motor. This code was also used for Chevelle/El Camino but I haven't seen a motor from Canada in one - yet.
Casting number is most likely 3970010 or 3970014.

Vintage,
Thanks for the reply and yes the block casting is 3970010 so is this block from 1970 and is it anything special like a 4 bolt main because we plan on a rebuild so unless it was correct for a corvette we are going to install a crate motor

111195930 appears to be the VIN derivative that match's the car that had this motor

1 - Chevrolet Division
1 - Model year ends in 1
1 - Oshawa Assembly
195930 - Production sequence number for the car

Not the original engine in the Vette for sure.

Forgot to include the year - like El Camino says, it's a 1971 year model and definately not a Covette original block.
Could be a 2 or 4 bolt - you'll have to pull pan to be sure. Wild guess would be 4-bolt, since the original application could be police or taxi.
Those year 3970010 blocks are good starting points for performance motors, be they 2 or 4-bolt.
Swap away!

k06 01 cgc

1971 CGC suffix is a run of the mill 350-245 HP RPO L65 with 2 bbl carb and a 3 speed manual transmission. Used in full size Chevy's.

350 Police and Taxi is CGJ suffix. The chance its a 4 bolt is slim but anything is possible.

El Camino;

I think CGJ and CGC are both 1971 H.D 350 police/taxi codes.
As I answered that from home, and don't have my decode sources here at work, I just 'peeked' at http://www.nastyz28.com/sbchevy/spcode2.html to see how they list them out and their data looks the same as mine - but both have been wrong before, so you could be right.
Why I think there is a 'possiblity' that it "could" be a 4-bolt, is that I repaired lots of these 'police' units as a Chevy line Mechanic for these years 'back-in-the-day' and this was a common block confiquration for H.D. police/taxi units then. The specifications for the repair of city/county vehicles stated that all engine blocks were to be of 'the H.D. design' (if I remember the wording right) and the county mechanics would check to be sure I used 4-bolt blocks for replacement of the 4-bolt blocks I took out of the police/sheriff cruisers, even though these were turd smog units. One of the mechanics once told me it was "Los Angles county sheriff's vehicle specifications" that stated this, but I never saw anything in print to back that up. I just may have to do a search someday to see if such a specification could have ever existed?
So there is a "chance" (not that it would matter) - as I stated.
Don't mean to start trouble - just 'clarifing'.

Thanks for the help so we decided to go with a crate motor since it is not the original engine but i will pull the pan just to see if it is in fact a 4-bolt main

Drum Roll Please.... :D

According to the GM parts catalog is not a Police or Taxi engine. Thats what I base my opinion on, also the interchange says the same thing but adds the engine was also found in the 1971 GMC Sprint which the 1971 GMC parts catalog says. In the GMC it was used with A/T. But this engine was not in a GMC, not were made in Candada in 1971.
