I have a thought.
Walk up to the core support and pull up and push down. Can you physically move the front of the car? You should be able to do this if there is enough travel in the shocks.
I had a similar issue on my car. My afco front shocks just stiffened up and quit responding to adjustments. They had always been flawless and you know how my car leaves.. One race I couldnt hit the tree and my 60s fell off. I fought it for several events. one day I grabbed the front of the car and tried to bounce it and I could not move the car.

I backed the top nut way off and could move the car. When I got home i pulled them off and put an old set of comp 3 ways on it at the tightest setting and it was night and day difference.
Now I have good shocks back on the car but that set bound up for some reason.

Its easy to check and eliminate as an issue.
