3400 isn’t too big of a stall?
and I’m pretty sure a 4l80e and 9" are creating more drivetrain loss than a t/c. I wouldn’t say 100 rwhp, but I’d say it would be around 570 rwhp with the light 10 bolt and t-56.
Either way, who cares about the dyno numbers… ET is where it’s at!! put that driveline to work!
