I ain't paying to watch it but I would throw out there that if the hemi was 440 CID and the 6 pack was a 426 CID we would never have a discussion about witch one made more power or was faster, slide 440CID under the hemi heads and the hemi then compare, nobody ever compares a 426 street wedge to a hemi.
I've built a bunch of BB and 426 Hemi motors over the last 40 yrs and I'm one of the unlucky ones that can get more HP per C.I. out of a wedge motor with good heads like ported 440-1 or B1 heads than I can get from a 426 type hemiriod motor with aluminum Stage V ported heads and similar cam, C.I. and combustion ratios And for a lot less money also Long live BB Mopar wedges
