    What 3.3 upgrades are you intending?You do know that the 3.3 chasis is longer than the 2.5 right?

    The 3.3 will drop right in if your truck has a 2.5 in it now.

    If your truck has the black transmission case I would also suggest using the 5351X Revo-spec slipper clutch upgrade.

    I’m new to nitro. Trying to upgrade 2.5 to 3.3. The truck is pretty new.

    If you have a 2.5 in it now a 3.3 will drop right in without any modifications.

    I suggest also installing part 5351X if you're going to a 3.3, but that's not required to get the engine into the truck.
