So Have 2 motors that dont run for opposite reasons. i have a D15b7 that has a bad head. And the other motor is a D16y7 with a bad block spun a baring. I dont have cash to buy a new motor. Both have good trannys. So my first question is can i put the D16 head on the D15 block and Frankenstein the two motors? Second question is can i use the D16 tranny on the D15 block if the head swap works?
