[ted]

Good morning gentlemen. I need a de-ciphering of my 1965 327 suffix code if you will.
block number = 3782870 dated B4 5 with suffix code 9X 3157 .
Not sure what the suffix code stands for??
What stock carb and intake came with this engine?
What stock cam came with this engine?
What stock points number distributor is correct for the engine?
What stock heads are correct?
Anything else re crank / rods / pistons # etc etc.

Thanks in advance gentlemen!! Yep a whole lotta questions eh boys. Could this'un be
an L79 block from 1965..
