EV question

[iceman5]

This is a real hand, but the question is a general one.
$2/$4NL at Party.

1 limper and I raise to $16 on the button with QQ. Only the BB calls. We both start with $400

The pot is $40. The flop comes T65. He leads out for $24. Based on previous play I put him on AT/KT. He has very few outs so I decide to let him bet for me and I just call.

Pot is now $88. The turn is a 4 (T65). All rainbow. He bets $40. OK, heres the question. Is it correct to just call again if Im pretty sure Im ahead and I doubt he will call a large raise? I put him on AT/KT but he actually had 33.

He has 10 outs to the straight or a set. I dont know if he would call a large raise but I doubt it so based on the theory of poker, is it correct to call here?

He did river a 3 and bet $90 which I called so I know what happens if he hits. I lose the $88 pot plus $40 plus another $90 for a total of $218 1 time out of 4.4 (10 outs is 3.4-1 right?)

If he misses, he probably checks so I win the $88 pot plus the $40 he just bet for a total of $128 3.4 times out of 4.4 times

$128 x 3.4= $435
-$218 x 1 = -$218

$435-$218=$217
$217/4.4= +$49 EV (rounded)

Is this anywhere near correct?
And even if it is, is this still a horrible reason to call him down? I mean, If I raise his flop bet, I win the hand, but the EV calculations look like calling him down is fine too.
