Cracked BB bell housing...replacement question

After pulling the 383 out of my 70RR I noticed a crack on the bell housing going from the outside of a bolt hole and across and down the curvature of the housing itself.The new motor will have around 400-450 hp...should I just go with a Quicktime bullet proof housing or find another stock replacement.I was hoping some of you experienced guys would have some advice...thanks

If your bellhousing is the stock aluminum 10.5", we have a heat treated 356 T-6 aluminum replacement, considerably stronger than the factory die cast:
