If you check out the ET's, you can see the 66' Belvedere Street Hemi
sedan with 7" slicks and stock camshaft ran 11.90's.
For the most part, if you took a stock 66' Hemi Belvedere 4-speed,
put in 4.56 gears, headers and 7" slicks, you should have been able to get into the 12.80's.

They were allowed an aftermarket higher lift cam in A/S (AA/S in 1967) in 1966. Most Hemi guys used the Racer Brown STX-23 (Chryslers recommened cam) flat tappet cam. Grumpy used an Iskenderian 550 flat tappet cam. Most ran 11.80's on 7 inch tires. I beleive it was Grotheer who used 2nd gear at the starting line to try to kill some of the Hemi's low end torque to get off the starting line better with those 7 inch tires. One of Stahls secret weapons was a NASCAR geared trans until Chrysler wanted it back which had a different low gear (somewhere around 2.20 instead of 2.66). That cause a lot of grief between Chrysler and Stahl as he didnt want to give it back.
