Cab - Google "engine masters gen 3 hemi" and it's in the pile of videos.
Short version: early 5.7 was markedly weaker than the later Eagle-head version, roundabout 80-some HP & TQ.
Both test engines were modified, early was carbed, later was OEM EFI.
Bottom line: grab an Eagle, the price difference and output are a better deal, and the Eagle's a lot stronger too.
I think that the later Eagle motor had an aftermarket cam in it too, which had as much lift and duration as the valve clearance would allow. Difference of about 6 degrees duration and .075"+ more lift. The Eagle heads flow 50cfm more and can make use of the bigger cam.
