Al, It sounds like the same problem I had with the 572 predator when I had a converter that was too tight for the head flow. Several things would help it besides that, but it would be cam, compression, can timing etc. I think you need a loose 8" converter. Also, put a piston stop in #1 and find TDC. If you are really running 48*, you already know that can't be good. Where does it dead stall? Is it lazy there too?
