Do I need a different bike? (C&V content)

I'm recently getting into riding as more than just a commuter and so I'm also more aware of bike fit. I've made some recent changes to make it more comfortable but I'm still feeling it in my shoulders and soft tissue.

Here are some basic points-
I'm 5'9.5" but I'm mostly torso. Inseam comes in around 32" barefoot, 32.5" in my cycling shoes.
Frame is 53cm seat tube, 54cm top.
170 length crank arms.

Being a man of mostly torso I worry that though my legs are comfy on this bike, my upper body is cramped. It's currently set up with a 90mm stem so I'm planning on swapping that out with a 110mm soon.
Saddle height feels good after measuring with the LeMond method. Fore and aft is troublesome though I may not even be on the right saddle. Recently my sit bones were measured to 145mm which is especially wide on an old Concor America saddle.

I love this bike .I built it up myself. Is it wrong for me?
Thank you all for your time. Pics below hopefully provide some help.https://cimg4.ibsrv.net/gimg/bikefor...4a8a5fc05b.jpg

You look good on the bike, nice position. Feeling it in the shoulders usually means move the saddle back some. May need an offset post if this isn't one. Soft tissue always means a different saddle. The Selle Italia MAN saddle fits a lot of people, very popular. Worth a try. Usually a good price on ebay. Looks like you could use a little more reach, not much, moving saddle back a bit might just do it.

Thank you! Saddle was going to be my next move before I swap out the the stem. It's sitting in the middle of the rails now.
I'll be sure to check out the recommended saddle as well .

You're sitting too far forward. I'd agree with moving the saddle back a few mm.

Nice bike.

Thank you for the second opinion. This saddle has pretty short rails but I can slide it a bit more. As I stated originally, I am also swapping out the currently 90mm stem for a 110mm. Would one of these adjustments replace the other or should I try both?

Your saddle position (fore/aft/height) comes first. Once you have that dialed in then adjust the stem to suit.

I'm the same size and proportions as you. I have wimpy shoulders and get upper body fatigue. The thing that has helped me the most recently is exercise. I do pushups and dead lifts and overhead presses.

Another very popular saddle is my favorite: the Brooks B17. I have these saddles on a few bikes. My commuter bike now has a Brooks C17 which I love equally well and is weatherproof. Brooks saddles usually feel best with the nose tipped up a bit.

I'm a motor mechanic by trade so I'm doing a fair amount of heavy lifting but maybe some real exercise is a good idea .

I hadn't considered the C17. The Specialized Power Saddle caught my attention as well. Maybe I'll try them both out . Thanks for the tip.
