Do I need an SFI bellhousing?

It is a loooong way off, but I am going to be putting a 4-speed behind my 422. I am expecting 500hp +/-, and it will be in my 73 Dart Sport 340 with 3.23 gears (note:the ratio isn't set in stone, but I think the engine will make enough torque to pull those gears pretty easy.) It isn't a drag car, but I will make some runs with it. Probably run some sticky tires at some point.

I will definitely be running a good sfi-approved flywheel, and a clutch assembly made for that kind of power and abuse. My question: should I run a Lakewood bellhousing also? I keep thinking as long as the other parts are up to par for that kind of power, the Lakewood bell wouldn't be nessecary. For the most part, it will be street abuse with a stiff suspension and non-sticky 17's. Opinions?
