72 Dart Swinger 3.6L Pentastar +T5

that if a new challenger you can get a 3.6 with the same transmission on the back of it as the 5.7 hemi and the 5.7 hemi bolts directly to a 727 or an 833 transmission then why can’t the 3.6. unless dodge transmission that they’re saying is the same for both motors is not actually the same.
They’re the same transmission with different bellhousing pattern. Same as you could get a 727 behind anything from a slant 6 to a 426 Hemi.
