360 swap from van to 74 Duster

you should be able t omove the wiring around to make it work,all the stuff you asked about wi be the same ballest resistor,,etc...do some measureing on the tranny,,,see where the cross member mount falls,if its the same style,i for got what year van you said was going to be the donor,,,

if you choose to get a short tail shaft tranny,,a 727 some times is a tight fit in an early A,.. usually all you have to do it snip and hamer the seam flat in the tunnel,, the 360 uses a balanced torque converter. if you find a short tail shaft tranny,, thats not from a 360 and it has a good converter you can get a flex plate from B&M that wil make it all work correctly,,

then the oil pan as mentioned,, must be from a car,, and must be from a 360.
the 273/318/340 motors oil pan interchanges between them but doesnt interchange with the 360,, good luck,, this is the place to find info,,,great site
