« on: March 31, 2018, 04:24:26 PM »From what I read that 4L just started when this car was made.
What that means is there where a few early Z/28's with the code 4P before they broke it down to further define the code.
All 1967 Z's had a 4 code.
Lack of any 4 code means it is a 327 car at this point with a 124 VIN start.
