Should I keep it ol school or new?(EFI or Carb. motor)

[allen123]

Ok Im going to be getting a new motor pretty soon because the vibration is getting pretty bad and im tired of having to but new brackets and mounts because it always breaks them
Here is what im thinking about doing
My cousin is really good with motors and he said he could wire up a late model motor (im thinking about a LT or Vortec)
Or should I just stick with a carberated motor?

Just looking for some opinions
