Putting the load of driving the blower that far ahead of the front main bearing is going to break the crankshaft, probably sooner rather than later. Of course, if it's only for show, that little issue probably won't present itself. The blower drive should have been the first thing ahead of the block, not the last. At least that's the way we built 2K+ HP unlimited class truck pull engines, and won a lot of pulls with them.
