Have been asking on the "other" Mopar site for anyone that has actually done the current 392 with 8HP70 swap into the '66/'67 Coronet. I have tried calling and emailing Holley multiple times with no response. They claim "minimal" tunnel "massaging" to fit the 8HP70 in on their swap videos. Can anyone really confirm what has to be done to put the 6.4 with the 8HP70 in (physically)? I know there are electronics required, just trying to understand physical fitment. (I hate to hack up a pristine floor-pan)
