Folks, let's not forget that most of those SS/DA and SS/EA Hemi "E" bodies all came with and most ran the 8 3/4 rear. Also the SS/FA and SS/GA 440 cars! Those guys were in the high 9's and low 10's 20 years ago!
Back in the late 70's Jim Kinnett made a 12 bolt live in his SS/AA Barracuda for MANY passes. They can be made to live.
