Performance can be worlds apart despite similar peak #’s. The 5.0 is 400 HP/410 LB ft weighing in at 445 pounds, and is backed by the 10R80. 5.7 Hemi is 5 HP less and 50 lbs heavier nearing 500 pounds, and backed by an 8 speed. Looking at the power bands, the 5.0 has a much broader peak power curve (peak Tq @4,250 and redline of 7,000 rpm) vs the Hemi (peak TQ @3,950 and redline of 5,800 rpm). That’s a big difference on the street from a red light. If you can’t substantiate peak power with a wide powerband it’s rendered useless on every upshift recovery.
American trucks just tested the Ford refresh for 2024, the 3.5 EB did 5.2 seconds and the 5.0 V8 did 5.5 seconds. The 10 speed is just an animal. I don’t think the 5.7 Hemi even comes within 1 second of either of the Fords, the 3.0 Hurricane S/O will probably tighten the gap a bit but it’s still backed by an 8 speed. I wouldn’t expect it to really set the world on fire, as peak #’s don’t tell you the weight it’s pushing against or the gear spacing it’s got to work with. The HO may set the world on fire though! High 4’s maybe?
