I just have a few questions on what parts need to be changed.
The first one is the motor mounts. I did a quick little search and haven't found the answer to my question. Are the 250 motor mounts the same as the 350 ones. And if they are is the only thing I have to do is to move them to the v8 position on the frame?
The second question- when I buy the crate motor can I run the oil pan it comes with or do I have to change it.
The third question- is the wiring harness the same?

Good questions, I've not done a 250 to 350 switch in my 84 yet. The previous 1967-72 the engine frame mounts would work but not sure of the 73 on ups. The throttle cable is different. You will need a V-8 shroud and radiator. The PS pump, hoses and brackets are all wrong for the V-8. Wiring is minimal, may have to be lengthened but I think everything should be long enough.

for the throttle cable do i just buy one for a 78 truck with a 350?
