Excellent result, our 589 pulled the same 1.9>2.0@5900>6000 with a 950HP, we made max power @only 5500 at 33 deg total and NGK 7's although it pulled to 5900 only losing 2hp. I would go straight to a Thumper BLP Dom with yours with that CR/cam, wouldn't mess with that 4150 if you have room under hood with a spacer and if you got any money left
