4.0L OHV to 4.0L SOHC

I know that the sohc is a 60 degree engine like the ohv but would the transmission bolt up up and engine mounts under the hood be the same???

I was wondering becuase once my ohv dies i am going to throw either the sohc or the 5.0L in there but as the prices if gas goes up it looks more like the 4.0L. But could someone find me some leads to my question or just answer it lol. appreciate the help.

Throw in another OHV. More reliable, and better low end torque. Direct bolt up too...don't go with SOHC.

Definately. The 4.0 SOHC is hella slow compared to the OHV, and even though it has more torque and horsepower, it doesn't really.

Its cheapest and easiest to go with what you presently have. If your OHV goes, find another one and bolt it in. No modifications needed and you know what to expect.

Theres presently just about as much for the SOHC in aftermarket as there is for the OHV. The ' power ' differences in the engines Are noticible on the top end, but down low or for offroading, the OHV would be the better engine ( IMO ). Pushrods beat overhead cams for torque.

A 302 can have just as good of gas efficiency as both of the v6 engines your speaking of. Some have an average of 20mpg on reports. I average about 12-15 with an SOHC thats been a bit modified. Others here have stated 15 up to 20. Different areas, elevations, air density.. many factors play in fuel efficiency, no 2 engines will have the exact same.

Once you mentioned ' econemy ', changing to anything different outside of a 4 banger means your not about a swap to something different as it will cost you more to swap to something else.. your looking to SAVE money, not spend more. for as many miles as you would have to drive to make up the cost difference.. it just wouldn't be worth it.

well the ohv engine only has more low down torque due to a lower torque curve starting at 2400 rpms then maxing out at 4250, and the sohc's torgue curve begins at 3000 rpms and ends at 5000 rpms, 160 hp - 225 ft/lbs or 207 hp - 245 ft/lbs, yes i do think that the ohv engine would be better for off-roading but the sohc makes 45 more hp at only 800 rpms higher than the ohv and an sohc spins up faster as well, but to put it simply i dont use my ranger for major offroading but i do like to turf the occasional corn field sometimes, heres a link for the ford cologne engine or better known 4.0L http://en.wikipedia.org/wiki/Ford_Cologne_V6_engine
