The mystery of the 396 engines in 1969
The 1969 model year is filled with a few knowns and many unknowns. For example, the number of different interior codes is known, the number of standard paint colors is known, and the number of SS396-optioned Chevelles is known.
What is not known, for example, is the number of a particular
iinterior trim codes were used with what body colors. What's not
known is
What's not known is the number of the three 396(1) cid
engine went into how many of the five available body styles/series
it could be ordered with. One can, by using math, get a figure of
how many 396 engines went into each of the five different body
styes/series by the percentage of those 'possible' of the total
Chevelles sold. In this matrix the 13427 series makes up 1.62% of
the total number of Chevelles (346,406). By multiplying the total
number of SS396 options sold (86,307) by this 1.62% gives you 1,400
units calculated as an even distribution of series vs. total.
The number of L89 options is 'ignored' here since the option required the L78 engine.
Note the number of 396 engines do not match the number of SS options sold. It seems sthat 323 more engines went into Chevelles than SS396 options sold. It's odd, the figure of 323 happens to match the number COPO Chevelles sold. COPO Malibu sport coupe build sheets show the L78 engine but NOT the SS option. Just why GM used the L78 engine as opposed to the L35 or L34 is the L78 engine generated other heavy duty equipment. Whether the L78 engine was ever installed in these cars isn't known but these 323 COPO Chevelles received the 427 L72 engine along with some other items like heavy duty suspension, a heavy duty 4.10:1 Positraction rear end, high performance ignition system, heavy-duty cooling system, aluminum high-rise intake, and a Holley 780cfm carburetor.
