The 8 should be a brick when you take into account the BUT range. Yeah I know he hit it, with a ridiculous 84o, but he only has two combos of K8s that would be reasonable, plus 9 combos of sets (4, 3, 8).
I liked your preflop sizing. With it going 3 ways to the flop, I might have made it a little higher on the flop bet, say to $45-50… tough not be results oriented here though. I might have made the call on the turn too FYI.
He’s the guy you want to play pots with, as he’s called off $14 more with 84o, and then calling a half pot bet, with bottom pair.
good luck!
