Power building? So, training like a powerlifter without the intention of competing?
Either way I see 3 big issues.
1- you haven't run a single program yet. You modified 5/3/1, used the wrong % or pounds for Shieko, and then you lost me after that.... all over the course of a year. One year. That's a max of 16 weeks on each half-program.
My suggestion here is to pick a basic program. 5/3/1 is fine, a basic westside program is fine. Honestly I'd try something like the Lilliebridge method because it's even more simple. And it works. Take that program and run it as close to as-written as you can for a year.
2- You bumped your calories UP to 3000 and wondered why you weren't growing? Eat, buddy, eat. The drug free 198er on my team eats around 3500 calories a day to maintain. As high as 5000 on days he lifts. I eat the same now as I did when I was 242 - I maintain on 6500 calories and grow between 10,000 and 12,000. That is mostly clean eating. None of my team eats fast food regularly.
3- You aren't committed to a goal. If you want to be big and strong then run a program to get stronger and trust that you'll also get big. Size comes with strength. Seriously - Keep it simple and quit wasting time on flys and curls.... maybe a set or two of hammer curls at most. Squat and leg press. Deadlift sumo and conventional. Deadlift off of blocks. Row and chin up. Bench and overhead press..... that's all you NEED, everything else is gravy and secondary to it.
