What year and type of motor do I have..

[Smokedawg]

I got my motor today and I wanted to check a few things...I took off the heads and its not a roller motor..I found some markings on the valve cover but couldnt find any on the block itself...I will look some more tomorrow..
The markings on the valve cover says: 2K318AA
Then the calibration #: 1-20N-R10
Then it had C44 punched in it.
It also said 8 degrees..

The motor was previously set up as a carb..

So what year of a motor am I dealing with?

I know it came out of a truck.

Can I make it a roller motor, I have a set of roller lifters for it and a X303 cam that I can put into it.

THANKS FOR ANY ADVICE!!
