Anybody put a Gen 3 Hemi in early A Body?

The guy said he didn't have to do any mods other than motor mounts to get that 1st gen hemi in his early a body, so not sure why it wouldn't work with a 3rd gen if there's clear evidence somebody made it work with a 1st gen. Then again, I don't know if there are significant size/design changes between the generations, but I'd say it's do-able.
