NL25: Villain overbet river after I give up

[Mr_Pathetic]

Reads are, I am super aggro at table but haven't shown down too much since people call to river then give up. So my question is will this be a bluff or AT,AJ,JT enough for me to make a profitable call since he overbet the pot? I think the only hand I am truly worried about him having is some kind of 8 but he was pretty decent so I don't think he will be calling PF with hands like K8 but might with hands like 98,87.
