86brick,
I suppose anything is possible with enough expertise.
The 9.5 compression would make up some power. Also, the lockup converter will help with ETs and MPH, if he actually locks up under boost. For sure, newcomers should take note of this combo, because I haven't read of or seen many turbo buicks running those times on iron heads. Not for long. One other point should be noted here is the fact the Formula in the article has a stock crank. The stock turbo crank doesn't seem to last long in the low 10s, but then again, expertise will help.
