Will 250 turn the stock starter? Seems like it would pop the first time the engine hot started and turned a little slow.
If that works for you then putting the relay next to the battery will work as well. Then the heavy guage wire does not need to be hot more thana few inches past the battery.
But with high compression engine you may need to run a disconnect or a larger relay and mini starter.
