I'm Awesome
With that cam you may want a little higher stall converter. If you do a power stand what RPM does your engine get up to? My OE converter only go up to 900, after I blew it I ordered a 2300 - 2500 stall converter (my cam is rated about the same RPMs) along with a 600HP stage 2 700r4. Be careful if you go with a cheap converter, you'll feel it slip and then lock up on partial throttle - kind of disconcerting. I also went from 3.42 to 4.11 gears, cut my times by 0.3 seconds, I was hoping for more from the gears.
Thats about right on the gears. My Hemi Ram dropped about .4 seconds going from 3.55s to 4.56s. My Express van dropped 0.6 but that was going from a 3.73 to a 5.13.
