maybe they did that to lower the car as well.one mustang i had with fe big block and c6,had big deep gouges on the bottom of the bell on it,and car 14 factory tires/wheels,so it sat pretty low.
in any case,if it was for 500 hp or more drag car i would not use it.ive seen what happens when a stock case bellhousing splits on the drag strip at 130,it destroy the car.it was a gm,so weak bell any way. so yhat must be weaker than stock.
