I'm thinking HP and torque...

My 98 Sport 2wd (ohv) tested at 172 at my uncle-in-laws shop and my 99 XLT 4wd (sohc) tested at 214. The only engine mod to them was a K/N drop in. He told me what the torque was, but I don't understand tourqe ratings so I don't remember what they were.
Just my $.02 and they are a year apart and one was 2wd and 1 was 4wd so that may make a diff too.
 






One has a dual over head cam, OHV, and the sohc has single overhead cam. the sohc puts out like 210 hp, just 10 hp shy of 220 produced by the 5.0L v-8
 






The major differences between the Ford 4.0 OHV and the 4.0 SOHC is the location of the camshaft. On the OHV (OverHead Valve) the camshaft is located in the block, between the heads. One camshaft drives all the valves. In an SOHC (Single OverHead Cam) the camshaft is located in the head. There is a single camshaft per head. So in a V-6 or V-8 SOHC, there are two camshafts.

The SOHC is considered a more efficient motor and, as a rule of thumb, capable of producing more power then on OHV. The OHV is considered by many to be a more durable motor then the SOHC. Give the option, I would choose the SOHC or better yet, the DOHC (Double OverHead Cam) like the one used in the Mustang Cobra and the Q-45.
:D

anyone know if the new 210hp V-6 (sohc) would bolt into a 91-94 explorer... I was told no because they had to change a lower frame set-up a little to fit them in.... anyone ahve an idea??
