Welcome, Paul - from another Wisconsinite!
Years ago I was thinking about putting a 392 Hemi in my '64 Belvedere when I came upon one for sale. After checking it out, it turned out to be a 354, and I didn't pursue it further. But, at that time I used the site below for some helpful information - especilly for adapting a 392 to a '60s era TorqueFlite. I haven't been on it in a long time, but maybe you'll find it helpful, too.
