With some diligent and patient FBM shopping, deals can be found to buy a used 8HP-70. I found one in Chicago for $700, but the seller never replied to me after I sent him an offer he accepted, so he lost out. Then two days later I was in central Indiana for work and searched FBM in my hotel room. Found a 8HP-70 complete with the torque converter, cooler hoses/tubes and complete driveshaft, came out of a 2016 Challenger with 50,000 miles on it, bought it for $400. Seller wasn't aware the 8HP would mount to any engine with the same bellhousing bolt pattern as a 6.7 Hemi. After I gave him the $400 I said I've heard of guys mounting the 8HP behind 318, 5.2, 360, 5.9, 340 engines. Then he said he should have hung onto the trans, heh, heh.
