Symptoms of wrong cam installation

With different posts I often repeat myself to often but October of last year I changed out a powerglide transmission and converter to test something. In my head I thought it was my old 5600 stall converter that I never got around to sending out to have checked when I put my new 5760 stall converter. Well my car was a Pig with the sixty foots slowing .06-.07 and slowing in the 1/8 from what should have been 6.01-6.03 to 6.32 and I couldn’t catch a light worth a damn. I ended up parking the car for the weekend. I just got that converter back and he said everything looked great inside. At that point I checked my RacePak info and it stalled at 4800 rpm last year. 1000 rpm worth of stall turned my car into a SLUG. Now I need another 5800 stall converter for a back up.

yep. Convertor being right is huge. That is why the first call i made( for my brother) was to the guy who built the convertor.
It factually flashes 3200. I told the guy( myself) exactly what the combo was, and that i wanted it to flash 5k behind it.
I also know that convertor being correct is super important when you are dealing with a 3400 pound, low ish compression 340 with a very big camshaft.
My brother is just ultra busy all the time. We will ultimately get to the bottom of what is going on. When he finds time to spend on it
