I have no proof other than a fond memory of riding in a black with red stripe 69 El Camino SS396 4-spd car in the fall of 1971 that had the L89 in it.
It was the nicest car in my high school parking lot, it was the 1st time I had layed my eyes on a big block with aluminum heads.
I tried to locate this car about 15 or so years ago but ran into a dead end, was told it had been totaled.
I still have memory recall about that ride. Today at 49 awesome, then at 16 cool.
