You can look at modern muscle cars they are about the same comp. just have a run lower boost levels. Newer cars run like 8 psi maybe 10 but that it due to their higher compression, I could be wrong on the psi but sure close.
Yea the only reason they survive is the ability to change timing anywhere in the curve. Hell with the right fuel and system I could run lots of boost, but then it turns into a race car at that point. Lol
