383 runs like a giant turd WTF

I have the same cam with TRW forged flattops,906 heads, edy tm-6, hemi battleship springs, 750 DP, gold ecu 36 total timing. 3800 9 inch convertor with 4.56 8.75. Barracuda was a dog after swap from 284/484. Degreed the 509 + 2 or maybe 4 (been 26 years ago)and she came alive. This cam needs a free converter and gears. Before I advanced the cam from the recommened centerline of 108 if my memory is right, she would not even break traction on the 275-60-15s.
