I've never played rush. Without history this would be a fold pre I guess, though you don't really have history I suppose playing rush.
If your calling the 4b, to ship over a c-bet on non A/K flops, you are definitly commited on this flop imo, villain will ship AA and AK, plus any FD's, if he got cute with something random like KQs and flopped a flush then u have a redraw, so just ship it imo.
Your in v.good shape vs 2 flopped flushes, which will be the strongest part of villains light 4b range, assuming he has one, and AK+ KK+

Hand 1: 26.760% 25.14% 01.62% 5226 337.50 { KK+, AKs, AsQs, KsQs, AKo }
Your still ahead if u limit his AK range to AKs (fewer combo's)

Even without dead money in the pot vs a relative unknown, especially vs one with fishy stats like this, there is no way you can fold, if u can't stack here u should most definitely be folding pre imo.
EDIT: I'm a full ring player, and not all that familiar with stack off ranges for 6m, though without history they shouldn't be too different, which is to say on the tight side.
Villains raise to $74 is a 4b, and that range will be much tighter then even his PFR range, his VPIP is only useful in determining he his a fish (by vpip / pfr gap), as his VPIP range is not his 4b'ing range.
The first hands that occur to me have got to be AsAx or AsKx. That huge reraise pre sure looks like something that I've seen a lot with AK.
This is a pretty standard raise size, this is a 4b over a squeeze, and the stacks are ~210bb's deep.
