Called Dyers

Called dyers blower service this morning, asked about the 6-71 kit price for a sb mopar polished set up. He said 4,100 bucks everything but the carbs, linkage, and fuel lines. I'm fixin to pull the trigger in January on one. Said they have no problems with dist clearance either on there kits. I told him what I was swapping it out for an he said those little B&M superchargers are highly sought after for sb mopars and I will probably get a good return on it. So my question is just how much better is a 6-71 blower then one of these little b&m's ? I realize 6-71 are bigger and probably don't work as hard to make boost but is that it? Surely there capable of more power right? Thanks.

Slow, if you haven't purchased yet, I might be selling my new 671 kit (all polished) since I am thinking of doing a black monochromatic setup in my 35 Ply. Feel free to PM me.
