I remember this one. With a good set of heads, the 440 makes one helluva strong engine. I saw quite a few hemis go down against the 440's back in the sixties. The hemi's had a very narrow power band that got started close to six thousand rpm while the wedges had it all the way thru.
Engine Masters has done a lot of engine pulls comparing them and it's obvious why the wedge engines did so well against them on the street.
