I have neither track times nor dyno numbers but...after a lifetime of hot rodding, I can verify that the combination of 3K stall, 4.10 LSD, JBA headers, Vararam intake, and 91 octane non-ethanol (w/o a tuner) absolutely transformed my 2011 Ram into a potent street brawler that launches hard on drag radials and pulls strongly through the gears. I am not saying this to boast
but rather to confirm the effect these few select mods can have on performance. There is some controversy about the benefits of short tube headers but the JBA's do synergize well with a high-stall torque converter, resulting in the beastly nature I described. In other words, these bolt-on parts flat work!!! Good luck with your project.
