Engine size on our 2017 Vegas

[Ricker]

There’s been debate between Triton V10 350 or 450 engine? The Ford book E-series offers both as possibilities. I heard in 17 they went to 350?
I was able to find the following info under the hood.
6.8 L which converts I believe to 415 cubic inch. Any experts have answers?

There is no 350 or 450 engine. E-350 and E-450 are just the designations for the chassis (E-450 is a heavier duty chassis than the E-350 one).

You are correct that the engine is a 6.8L V-10 (2-Valve version 305 HP/420 ft-lb Torque).

I'm not 100% sure, but I believe all the 2017 Axis and Vegas were built on E450 chassis.
