Years ago, I used to help a local racer, who ran 65 Big Chevs in Super Stock. This was in the early-mid 70s, his 65 Biscayne ran SS/KA with a 396/325, he later swapped the running gear into a 65 Impala wagon, which ran SS/LA, I think it was. I remember he ran a Turbo 400, which unless I am mistaken, was the first year for a 3 speed in a Chevy? Back in those days, S/S cars had to retain stock style rear suspension, and those cars had a habit of ripping the upper control arm brackets out, even the BB cars, that had 2 uppers.

I hadnt thought of the upper control arm issue.

I have seen examples documented of the big Chev in SS/Auto, not so much impact loading, but it seems indeed the loading was too much to launch a winning stick car.

There was a T400 L72 for its final year 1969 only but it looks like very few were built like under 100. I dont see any of those in the win sheets either for 1969-71 but as I pointed out I'm missing a few event results from those years.

Do you have a link to Dwight's site you referred to?
