I know its the 305 5.0L, but more specifically i want to know if it is the LG4 or the L69 (high output). How can i figure this out? I'm really hoping its the L69, but most likely isnt because my grandfather only bought it to get to church and back.

Your 83 Caprice has the LG4, 305 4bbl, aluminum intake. The L69 was only available in the Camaro Z-28 and the Monte Carlo SS. From years 1984-1986 or so. I had a 84 Z with that motor I rebuilt and put in my 78 Nova Sedan and it really goes nice.
