Well, ZL1.FUN, I beg to differ on your V8 Biscayne production total. My GM documentation shows that there were 148,101 Biscaynes built. From that total there were 54,601 V8 Biscaynes built. You may have overlooked the V8 Biscayne wagons. Granted there may not have been any L72 Biscayne wagons built, but the wagons would have to be included in the total because they were V8 cars. And then we run into the same 'ol thing "who knows for sure?". Here's what we do know.

Biscayne production- V8

2-door sedan mdl 15411 - 12,165

That brings the total of V8 cars to 1,147,165 units, 2-door V8 cars to 568,598 units. Most if not all of the 1,856 L72's were probably put into 2 door cars. But, there is knowledge of at least one 4 door car that was built. I don't remember what model it was. The Biscayne had the lowest 2-door V8 total. That being said, it doesn't mean that the Biscayne would have the lowest number of L72 cars. Probably quite the opposite since it was one of the lightest cars in the bunch. In fact the 1966 Finger Tip Facts shows the Biscayne and Bel Air being virtually the same weight. The others get heavier on up. It's tough to make a guess since there are so many variables. If you go purely by production totals, most would be Impala Sport Coupes followed by Caprice, then the SS, etc. But with racing in mind most people went with the lightest, most stripped down car. So that would blow the production total guesses out of the water. The lighter car guess makes more sense. With the Biscayne and Bel Air being the lighter cars, most of the L72's probably went into those. Maybe in the range of 500-600 each, maybe a little more or less. Remember that's a guess. I even heard that some guys ordered the cheapest car with the L72, only to rip it out of the car and put it in something else!
And yes, there were L72 Caprice's. I own one and so far have tracked down 7 others. My post with the other 2 cars is probably still floating around.
