Tremor with 4A, front LS, and open rear diff w/electric lock is impressive in snow, (and mud). Sits a little higher with a front bash plate, no motorized air dam to smash, and rides a bit softer. Transfer case mechanically locks into 4hi/Lo like Raptor to avoid overheating clutch pack. Sits higher, big wide running boards too. Would be my choice (plus keep 350 for heavier long distance tows).
3.5 torque is rated 100 ft/lbs more than 5.0. Another Tremor difference is they come with 3.73 gears (at least in 2024). Think only 402a option in ‘24 was the sun roof I don’t care for. Beware present 402a options stuff you may want that come with King Ranch, dealer stock is likely to be missing things. And Tremor color choice is limited.

2024 402A 3.5

 

This is a super hotly debated topic around here.
Personally I went with the 5.0L V8. All the local mechanics around me recommended the 5.0 over the Turbo V6s for reliability. Most Ford mechanics I have seen online recommend the 5.0 V8. Not to say the others are bad engines, but consensus across the board from what I have seen is that the 5.0 is the most reliable, especially the 3rd gen and up.
Plus if you like a nice rumble from the exhaust, the V8 definitely wins in that category.

 

Just an observation, the 5.0 has all the modern equipment, 2 OHCs, 4 valves per cylinder, direct and now port fuel injection, aluminum castings, electronics, that the 3.5 and 2.7 use. Big difference is the V6 are twin turbo and the design is 15 years old. The 5.0 puts out nearly the same torque as the 2.7 and much less than the 3.5 and the V6s produce torque over a thousand RPM lower. If buying a F150 after 2023 the 10 speed parts have been fixed and the 3.5 phasers also. A 2026 has the latest transmission programing. The 5.0 is a great engine in the Mustang, but in the F150 most use is torque dependent and both V6s deliver torque better. The whole reliability argument surround the turbocharging, which has been is production from other makers since the early 1960s. Turbos just have seen little use in light trucks except for the IH Scout of 1965. The turbos get blamed for poor maintenance (oil changes and air filtering) simply because most service techs have never dealt with a turbocharger.

Idaho Fred, any of the F150 engines are good, but the TT V6s are better at truck things that the peaky 5.0 V8. All have been in production almost the same time frame except the 2.7 (which as the smallest of the bunch has a proven good reliability). If you are looking at towing check out the capabilities of the 3.5, it is substantially better than the 5.0 in torque delivery. KM

 

All the debate and opinions as far as reliability are just that: opinions and nothing more.

Pick which engine best suits your needs and go for it.

 

Thank you all for weighing in! Much appreciated.
