4.2 v6 vs. 4.0 v6
#1
#4
I used to have a 4.0 (pushrod) motor in a Ranger. Strong running little truck.
IMO, the big difference is that the 4.2 has a 90 degree V, while the 4.0 has a 60 degree V.
The 60 degree V6 results in a more balanced firing than a 90 degree 'odd firing' V6. While the 60 degree V6 is not natually evenly balanced like a 90 degree V8 is, the 60 degree is closer and therefore sounds a bit more like a V8 than a 90 degree V6 would.

The Ford F150 Essex V6 engine (4.2L 205-210hp) is an even firing engine. The Ford Ranger Cologne V6 engine (4.0L 155-160hp) is an odd firing engine, just like the F150 4.6L and 5.4L. That’s why the 4.0L Ranger sounds more like a V8.
Even firing engines alternate fire from left to right. Odd firing engines have two double fires on the same side. Odd firing pulses double the exhaust output on the same exhaust bank during rotation. The added exhaust pressure unbalances the exhaust system, which is why odd firing engines need “X” pipes, “H” pipes, or a “Mac Chamber” to re-balance the exhaust.
Both engines have good power to weight ratios. The Cologne was built for smaller engine compartments (cross plane crank and 60 degree angle) to fit Taurus, Explorer, and Ranger. The Essex was built for weight (single plane crank, 90 degree angle) Mustang, Thunderbird, and F150.

Sounds like you know your stuff so I ma not arguing but are those HP numbers at the wheel? My '03 Ranger 4.0 was rated at the crank 207, just an fyi. I am speaking of the '01+ SOHC in the ranger, not the OHV in previous years.

Yes, but is not the firing order the same for the 4.0l ohv and SOHC as well as the 4.2l which would be 1-4-2-5-3-6. Aren't all of them even firing? Also, the poster said he thought it was a newer FX4, which would make it a SOHC?
