I have a quick question. I recently aquired a 83 w150 cause the price was right. It has a 225 slant six in it which has started going down hill in a hurry. I want to put a 360 in it. The truck has a np435 trans that i would like to keep in it. I know that the bell housing will have to be changed. My major question is wether the input shaft to the tranny is the same between the two engines?
