What in the World is a 454 Hemi?

The early 1950's Hemis were popular with drag racers. Not sure why. Sounds like that might be what he had. I imagine a major design problem to install one in a 69 Charger and might not even fit. Anyway, no harm in him talking and dreaming. Many wait for retirement, then end up sitting on the couch watching daytime TV instead. I would guess 3x as many unfinished projects as drivers (my wife likes to point at mine).
