My thought is will a3.5 Ecoboost bolt into a 2021 Bronco with the 10 speed Auto?? If so that's the the answer for more horse power. Anybody now the answer?

I agree

With companies like 5-star getting upwards of 500HP out of a 2.7 swapping to a 3.5 might not justify the expense. If you need more than that might as well go big and shoot for 750HP +

The 3.0L seems like a better candidate since it's based on the same block as the 2.7L. The 2.7L/3.0L was designed from the ground up to be a turbo motor which may set a higher ceiling. The 3.5L was originally an N/A motor that had forced induction added after the fact.

Anything can be done, but the 3.5 and 2.7 do not share any parts. It would require a full donor motor, exhaust, harness and all associated sensors at a minimum. Tuned 2.7 is good for 400HP and 450lb ft. of torque. That's pretty beefy without anything but a tune and intake. I think it's capable of 450HP and almost 500 lb ft of torque with additional tuning and bolt on exhaust (starts to get touchy on 93 octane fuel or even require E85, which for a daily driver, makes fuel range pretty low).

The 3.5 will spank the Hemi with those numbers.

I hope they offer an option like the power-boost that will be in the 2022 F-150 and is already in the Lincoln Navigator.
on the F-150 forums there is video of this hybrid-electric motor running 0-60 in 5 seconds. Faster than the 3.5 HO in the Raptor.

If I wanted more HP out of my Bronco my first thought would be bigger turbos and a tune. Lost easier than an engine swap.

If you have the money literally anything will bolt into anything!
