440 blower manifold BDS or Hampton ???

No pics right now sorry guys. I got a 6-71 with two 750 edelbrocks off Craigslist. I was going to put it on a w2 motor but that plan changed. I am putting it on a 528 -440, I need to have spinning assembly balanced and put it together with either ported edelbrocks(I have) or going to buy a set of 240 trick flows. The Hampton is a 2 piece welded deal, 6.3 in tall $825 polished, The BDS is 3.3 in tall, $710, polished. I had been toying with the idea of a blower spacer but wouldn’t need it with the Hampton. Going for 9.3 compression and only 4-5 lbs of boost. The 6-71 is going to have a hard time making boost on 528 and I’m not going to push it.
Nice ! 70Duster440, real nice setup! Any pics with a hood on your car? I like that throttle linkage, who makes it ?
I’m putting this in a 70 Dart with Fenderwell headers.
