Update***
So I did a fuel pressure test yesterday..Idle PSI was 58. Under load I would regularly see it drop to at least 52-54 PSI on pulls but I did see it drop below 50 a couple times WOT.. Didn't get a chance to check the regulator yesterday tho

Looks like you've found the problem. Now it's just a matter of determining if it's the replacement pump itself that's failing, or some other part of the original stock assembly that's causing the issue.

Just an FYI, there isn't really much performance difference between the 2.73 and 3.23 rears in the 4L60E cars. I've owned two of each. The 2.73 cars actually aren't much slower, 1-2 tenths/1-2mph with the stock torque converter (less with a 3500+ stall). It wouldn't make the kind of difference you're talking about.
On the other hand, if you put a 2.73 rear with the T56, that might feel pretty sluggish, especially with a cam, in the lower rpms. But I don't think you said anything about changing the rear/gear during this process (or did I misunderstand?)
