In 1968 they made 327's with this casting number but they were only 2 bolt main.

Then from 1969 - 1979 they made 350's with this number and they were either 2 or 4 bolt main.

If it's a 4 bolt main, then you know it's a 350.

To determine exactly what you have, you need the block "suffix code".

It's on the front of the engine, just in front of the passenger side head. It's on a machined pad only found on that side of the engine.

Looks like you're in Ontario, I see the codes as:

K=St. Catherines, Ontario
10=October
18=18th day
CMJ=Either 1974 350/4 bolt, T-400, Police or 1980 305, you need to find the production date or ensure it is in fact a 4-bolt.

I have a 3070010, 4-bolt.
And from what I could gather on mine, it is a 350, with straight drilled mains "Not Splayed", and the 010 casting supposedly indicates that it has a higher nickel content in the cast, making it a stronger cast.

I dont remember exactly, but the front pad stamping said something along the lines of "67-68" car engine, hope this helps
