GenIII Hemi w/5-Speed Supra Trans?
They use the dakota ax15 bellhousing on the small block. Also Advance adapters makes an AX15-ford bellhousing plate. In theory that could work w/ a QT bellhousing for a ford TKO. If that plate will fit the same on an R154
I believe +/- 500hp was about the limit in the supra(MKIII?) and those supras were surprisingly heavy.
