priced to call in BB with junk

1/3$ playing like a 5/10$ (max buy in 500$)
9- handed pretty late at night 2 or 3am table is deep lowest stack with around 1200$ highest around 3k$ most have around 2k$ pretty much all the winners from other tables just all table changed to this one. Couple of guys are drinking just having fun visitors I would call them. Two mostly winning regs (UTG V1 and HJ V2) and a super tight older passive 60s NIT only aggressive after all cards are out (Button V3). Rest are just rec's that play alot.

I thought this was a pretty interesting hand because of how big the pot got on the flop.

Hero in BB 1, 900$ picks up 4d7d

UTG (MAWG 40's winning reg 2k$eff) opens for 15$
calls around to hero who calls (really wanted to squeeze but just too garbage a hand to do so.)

board is super pretty 5d, 6d, Ac (pot $135)
(hero has plan to check raise this hand even on the double draw)
x, x, UTG (V1 $2k eff) C-bet 25$, fold, fold, fold, HJ (V2 $3k eff) calls, fold, Button (V3 $2.4k eff) calls, fold, Hero 105$, calls around

turn 8c (pot $660)

I've got V3 on most likely with a big ace or possibly a nut flush draw diamonds or at worst a set. We have a possible weak ace from V1 or a mid pocket pair most likely not a set or I would have for sure seen a 4 bet. V2 is a bit trickier and could have A, 7 here improved his hand and I could be at worst chopping with him if he catches up. I cannot really put V2 on much more then a weak Ax or a second/third nut flush draw like a KQ, KJ, QJ, J10 dd.. I've seen V2 raise large on a nut flush draw before on a couple occasions this is his typical line.

Plus so many limpers pre I can't really see any of these guys holding something super nutty. I tank for a while to think about what UTG's plan is here and if I should go big or small here to induce a re-raise. I want to pot control as much as possible but also don't really want make it too cheap to catch with two flush draws on board and most likely a set looking for a pair I mean I cant fold at this point regardless of river right?

Hero ($1789 eff) goes with lets take it down and bets $800, V1 folds, V2 folds, V3 calls ($1.5k eff left) ?!?!?

(pot $2260)
river Kd (just absolutely the most gross card I could have possibly seen)

Hero? (about 1k$ left)

Thought process here is V3 could have ak here and jam yes seriously jam with just top two or a set even though I had a straight and now have a crap end flush. I feel like a check will make him jam me too. I'm 900 or so invested already do I just jam here? Do I bet small... really dont know what to do here I tanked for a good 3 minutes before I made up my mind on what to do. Old guys beady eyes in glasses just staring me down the whole time. I know he has a big hand but does he have a shit big hand is the question like top two or a set.

Help fellas???
