383 runs like a giant turd WTF

I had a similar set up in my Barracuda and it had NO bottom end, I switched to the smaller mp 484 and an m1 dual plain and it was a different car, It became a frigging beast.

I forgot to mention I also changed out the original carter avs for a 700 Holly DP at the same time. Yeah it was my first build and I had the setup all screwed at first but after I got it figured out it was on.
