Aluminum vs Cast Iron bell housings

A Lakewood definitely requires surgery; an Ansen less so, if I remember correctly. I agree the QuickTime looks promising, but have not had the opportunity to try one either. (Don't you feel like we're dating ourselves by even remembering Ansen "Blow-Proof" bellhousings??:))
I still have an Ansen to go in the 66 next engine I try.
