nl400 LIVE jto otb multiway big flop decision

[ThroXerioN]

preflop a tight and pretty straightforward player raises to 14
i call otb with jto after a few callers in front of me.
We go to the flop 5 handed with 76 in the pot

flop: 896 rainbow
original raiser bets 60 there is 1 call and i call too,
then sb shoves for 360 total, original raiser hesitates a bit and then shoves as well for 440 total

i put the original raiser on an overpair (most probably aa or kk) but i cant be so sure about the small blinds range since he was the biggest fish at the table so i guess his range does include some two pair combinations and not only sets.
so now i have to call 300 for the mainpot and 80 for the sidepot for the main pot im getting about 3to1 and in the sidepot im not getting proper odds but in comparison to the big main pot its not too much im losing.

am i getting the correct odds to make this a +ev call or should i avoid such a huge gamble?
