Hello
I'm getting ready to go from a 350/700r4 to a 5.3/4L60E in the near future so my question is being that the 700r4 & 4L60E are almost the same thing other than the electronics will I have to modify my driveshaft in any way?
This is going to be done on a 1969 SWB fleetside & it will be my first swap.
Any feedback would be appreciated.
Thank you
