4.0 - 3.9 - 4.7 Different bellhousing bolt patterns?
Just looking for a quick confirmation here...
The 4.0 6 cyls, the 3.9Magnum series motors and the newer 4.7 family allhave different bellhousing bolt patterns, yes?
I heard the 4.7 was the same, now I hear it isn't. Is it the same as either the 4.0 or 3.9 Magnums?
Looking into a close ratio NV3500 for my 98 5.9 ZJ.
The HD is a good choice but it seems like there are BH pattern compatibility issues. I don't think they were behind motors that fit the Magnum B/H bolt pattern.
