Just replaced the engine block in my car listed above, GTP. It had a boost issue after first start, I fixed that issue and the next day it won’t start, won’t click, all lights come on as usual, starter has power and ground. Brand new battery and alternator, starter is 1 year old, I’ve checked everything I can think of. Any ideas?

It sounds like the starter has gone bad but to be sure let's check for power at the solenoid trigger wire.

Here is a guide that will help:

I’ll check that when next. I got the starter tested and it works fine so I believe it’s wiring.

Yep, it could be the positive or ground battery cables, it would check those first.

Okay update. We got the starter to click with key, battery tested good, but it still won’t crank the engine just clicking the starter.

I would put a breaker bar on the front of the engine to see if you can turn the engine by hand to make sure it is not locked up. Let me know what happens.

I’ve tried that just to be sure already its turning over fine, I was think it might need to be shimmed but I’ve replaced the starter a couple times I the past and never had to.

I don't think a shim will fix it, they have not used shims in years. It's got to be the starter or battery cables, I would put a test light on the positive cable at the starter to see if it stays lit when cranked over.

Also, can you confirm the trigger wire is getting power when in the crank position, did you go over the guide I provided?
