that video is useless because in no way shape form or fashion can you compare the motor to our motor. yes everybody says 1 3/4 are better for our trucks and I also have 1 7/8 but in a 8 speed 3.92 you spend way more time in the upper rpm range with that combo than with other combos hints the more time your in that range the more power you make for a longer amount of time which makes you go faster or at least the same for less cost. what I'm getting at is I bet there isn't enough difference in the two hp wise and the cost difference is pretty substantial but if your running say a 6 speed with 3.21 then I'd say 1 3/4 but an 8 speed any gear I'd say both would be fine and I'd bet the 1 7/8 would be a little better up top oh and also Matt has said before that 8 speed 3.92 is a whole different animal and 1 7/8 will do just fine. obx is half the cost

I think most people don't take into account that there are so many variables, I think Engine Masters is kinda on to something still but yet they didn't test all the variables also.
For most people their need and desire and capability to test or use that power, they will never really see the difference or know. But for people like Matt and other drag racers or tuners I think they will because they are constantly changing parts to find that next 10th of their time. Something Most will not take the time or spend the $$$ to do.... It is expensive to truely test and tune a motor and once you change one thing you can upset the balance of another...
For the Average guy I think either will work but the 1-3/4 is recommended due to the typical use and butt dyno feel to make people happy...
If someone is building a purpose built Ram then they need to look at all the variables and will prob be changing and tweaking things constantly and what they experience may not parlay to another novice that only has 1/4 the mods....
in summary just gotta do our homework and see what fits our build and use
