No, I don't. Flow benches and dynos were a bit rarer than they are today.I don't think I used T heads in the 70's .I just used whatever came on the engine cores.
I remember hearing that Jerry McClanahan had a 520 on one side ,and an 896 on the other, and he was the R/SA record holder.
Today when building a 283, you throw away most of it... You might use the block in a low budget operation..Maybe the crank for a core.. Don't need anything else..Truck heads, 327 intake , any venturi clusters in the carb, etc. ;-)
