Do I need to run an adaptor plate to mate the 518 to a 5.7 Hemi?
I have seen several threads and I can not confirm for sure if this is needed. Street and Performance shows and adapter kit but I am not sure its for my setup.
I have no idea, though I'm told the Gen III Hemi has the same bolt pattern as a small block mopar and just needs a flexplate which Mopar Performance sells.
