4.0 SOHC on 3.0 five speed

[KyleTay]

Will the 4.0 SOHC engine mount to a 3.0 five speed?

Was looking at buying this 3.0 five speed and sticking my 4.0 SOHC in it

No it won't.

Keep looking.

FYI: The 2.9, 4.0l OHV use the EXACT same bolt pattern. The SOHC is very close to these, 7 of the 8 bolt holes line up.

well, I kinda found that info soon after I asked. If 7 out of 8 bolts line up I would be very happy, but will the clutch and all that still work together?

The clutch spline and disc size is the same between the SOHC and OHV. The flywheel on the early OHV is 6 bolt, The SOHC (and later OHV) uses an 8 bolt flywheel. The same disc and pressure plate can be used on either flywheel.

The older OHV used a weaker M5OD as does the 2.9l. The 2.9l M5OD has a different 1st gear ratio.

The later M5OD-R1HD is stronger, but I dont know how much stronger. Maybe someone else can let you know.

according to the dimensions im finding the sohc clutch is slightly bigger 10 1/8" vs 10" on ohv idk if thats to make a huge difference.
