You've seen my 3400 258mm flash to 4k+ first hand... You've also seen it footbrake to 3600.
I still tow with mine and its 258mm. Rarely see a temp over 150 with my Tru-Cool. That's through a 6l80e too.
I love my stall. I couldn't ask for more. I'm glad I didn't go higher. I made up for keeping the stall low by getting it made "loose"

So would it be safe to say, I could pick up 3 tenths just by swapping out converters?
slowly getting somewhere, 12.75 @ 105 1.77 60', 414rwhp/417rwtq
I'm running the 3600 3c and with the setup in my sig with 150 shot I cut a 1.64 60' but that is in a rcsb. Still stock 5.3 with just boltons, gears, homemade traction bars and right at 4000 lb race weight without me in it
