Battery hold down

[cavell]

previous owner put in bigger battery and cut out the ribs to hold edge of battery. And had no clamp so battery was just bouncing around. Time for new battery box and proper battery size. And he cut out tabs on battery box top so it could not connect to lower box. Pcm tray was just bouncing around.

got new tray. Sound is 10% less from battery moving? Must be something else. Least battery is secure.

Heads are on. And intake.

Thermostat is 180f. Should be 195f.
Previous owner was chasing overheating issue.

Chasing rattle sound. I found upper trans mount which is under battery tray. Maybe that is culprit? I do hear click/clunk when I crank motor. Thought maybe starter had issues? Is motor rocking when I crank it?
