    You can do that now, no need to wait for 2019 parts, just swap in the pumpkin from a 6spd Challenger.

    You will need a tuner.

    Forgive me..... last question about this...... as I do not wish to take this off subject too far, but any recommendations? I'd rather ask someone who has experience than to go it alone and choose an inferior tuner..... if okay?

    For basic canned tune, Diablosport is the most popular and probably most effective.

    For dyno tuning, the choice grow quickly from Diabo to SCT to HP Tuners, to Syked.

    The very popular Tazer by Z auto does not change rear gear settings in the computer.

    If you want certain electronics to continue to work properly. Wheel speed will be changing based on rpm.

    What won't work on the 8-speeds changing the rear gear?
    As far as I know the wheel speed sensor is not within the trans, thus no impact changing rear gears unlike the Merc 5-speeds.
    Thus no programmer needed as I understand it.

    Are you referring to the upcoming GT500? The GT350R is listed at 3,650 lbs. It's possible that the GT500 will go even more upscale with weight shedding and lightweight materials. What is a Hellkitten listed at? 4,480 lbs? Unless my math is bad, you guys are being very generous with the 500 lbs. figures. Realistically it's more than that.

    This explains why a $37,000 2018 Mustang GT with the 10 speed is giving the 2018 Challenger Hellkitten fits at the local tracks, much less a GT350. I fully expect the GT500 to dust it like a coffee table.

    Power is awesome, but there's a lot to be said for shedding weight. I love the Charger/Challenger and if I had money laying around I'd go buy a 392 Charger tomorrow. But my 16-year old Mach 1 still runs with the Scat Pack cars, and it's all because of the weight difference.

    You're forgetting (and I owned a GT350 for 2 years) that the Shelby is manual only. It's significantly slower at the strip than the new sport automatics, even in the hands of the very best. The car is NOT setup to drag race, but really for a street circuit.

    No real surprise that the 2018 Mustangs with the power bump and 10-speed auto are running great times. They also made the magnetic suspension from the GT350 and the wider wheels and tires available on the GT. Those are huge advantages over earlier generation Mustangs, especially when launching on the strip. Switch to a set of street legal drag tires from the Michelin Pilot Sports or Cup tires and the Mustang GT is damned fast.

    You may be right... I’ve personally never tried it on a 8 speed car.

    The normal Scat Pack's have a 3.90 rear axle ratio so I'm wondering why the 3.70 is such a big deal...

    Yes, but we were specifically talking about Scat Pack. Previously the R/T six speed with 18” wheels was available with the 3.70 gear also.

    Point being a Scat Pack owner can look for a Hellcat M6 takeout for swap if wanting the same 3.70 rear diff as the upcoming Scat Drag Pack.
    Actually probably would be best to just swap in the whole rear Hellcat cradle.

    Not sure the R/T rear diff is interchangeable with the 392 cars.

    No Widebody, no dice.

    Give me essentially a Demon, but with the 392 (or hopefully 426 soon) and call me happy. Trans brake included.

    If I remember correctly, Charger Mopar '11 had a 3.92 rear axle ratio as well.

    Yes sir I’d have to go back and look at the spline count for the R/T rear.

    So many guys use the Scat Pack 3.09 on A8 Hellcat’s... Shouldn’t need to swap the whole rear cradle if using a M6 Hellcat rear on a scat, but my need to grab the axles. Scat Pack has the same rear brakes and hubs as Hellcat.

    Good tech talk!
