does not compute. The suffix is often three letters, like CLL. Check them again to see if it's CLL and the horizontal parts of the "L" are lightly stamped or something.
- '73 350 Camaro 245hp Z-28 TH400 4-Brl w/A.I.R.
- '77 350 Impala 170hp LM-1 TH350 4-Brl
The date code will narrow this down more if it's actually CLL. The date code will look something like "D 11 3" or "B27"
