They are a touch wider than a 440. But they are shaped like a hemi so the width is at the edge of the heads. It's tight in my Coronet. I've not sat it in the fury. A fusie wagon got an early 5.7 on the old cbodydrydock.com, don't know if the thread is still there. He used the bigger and less useful truck trans. Factory AC may hit the k member. Factory alt location may hit suspension.
It is just a 347" so the torque curve isn't the same, the 5/8 spds matter. We are thinking of doing a 392 with 4spd OD in my brother's Charger, but I probably wouldn't with a 5.7 without boost...
