DISCLAIMER**** (lol)OK so in our shop we dont do a lot of redesign so Im having a really hard time with this. Its been a while. Most of the changes we make are firewall changes and trunking. Im having a huge brainfart on thsi.
To the point: I am trying to ping across a trunk from one 3750 to another with loopbacks. Where am I going wrong?

interface Vlan1983
ip address 192.168.83.1 255.255.255.240
interface Loopback1984
ip address 192.168.84.1 255.255.255.255
vlan 1983

It is possible that there is more than one issue in this. But the first and most important issue that I see here is that there is not interface on switch 2 that would cause EIGRP to carry over the trunk.

In your original post 192.168.83.2 was assigned to a loopback interface. Are you now suggesting that you have removed that loopback interface and put the IP onto the vlan interface? I would think that this would work better.
It would be helpful if you would post several outputs so that we can better understand what is going on. Please start with the output of show ip route from switch 2.

Hello,
Even though eigrp is configured have you enabled ip routing on the switches
