Love your work on Jason's cars, Mr. Klockau. This iteration leaves me nostalgic for the 1972 Impala which I owned and drove during the mid 1980s. It had the 'siamesed' 400 small block with a two barrel carburetor. On a short highway trip, it once averaged 11mpg. The ride and handling demonstrated the aptness of its "tuna boat" designation. I eventually replaced it with something tiny and happy to turn and bearing a manual transmission. Nevertheless I sometimes shop the web for B-body convertibles, and dream of the fun to be had.
Love the car. When I was a little boy my parents owned a 1970 Capprice Classic that was a convertible. Had a 350 with an automatic, burgundy with a white top. We lived in upstate NY, finger lakes region. Have never seen another and I'm now 55 years old.
Great find! A friend's father had a '70 Caprice with the 396 in it. We tested that big block a number of times. Bet that 454 is even more test worthy. Why am I attracted to these big block cushy GM cars? Oh, maybe that 420 HP Escalade 6.2 liter in my garage says something about my preferences.
