340 stroker 422

Axle ratio is 3.91
Cam after retarding 2 degrees came out at 104.5 icl
I was thinking to install it at 106+

At 108 your overlap triangle is centered (where it should be) and you are closing the intake valve 4 degrees later (@ .050) and that’s two big things.

I also question your gear selection. Unless you have a very short tire you will constantly be lugging the engine, or at least be far enough below peak torque that you are on the edge of detonation.
