Has any one here done this in a rangie classic, replace a 3.5 with 4.4, or know how it would work.
I think the flex plate would be different as the 4.4 was fitted with Borg warner 35 trannie.
And if it can be fitted is it a good match as in shift points etc?
Cheers

It has been done , you will need a crank to torque converter adapter/ spacer , the 4.4 should make the 727 work alot better without sapping too much power.
