Currently, with my 3.07:1 axle, the 617.950 pulls hard in first and as soon as 2000 rpm comes up, I am developing 14.7 psi of boost. The 1st gear downshift is critical to having a 'peppy' 617.
I am preparing to swap in a 2.47:1 and 1st gear start is even more critical with a tall gear in the back...
