Poormans quest for 7's w/...406?

I wanted to mention this in my previous thread but figured I already had plenty on the plate. If you didnt see the other thread, the current plan was wake up my 383 and back it buy a good th350 or 400, 3000+ stall, 4:10's, lock right differential, with 26in mickey t ET drags. I didnt mention however that I picked up a excellent condition 400 for $150 a year ago. I had it bored 30 over and havent touched it since. I don't know if you are familiar with the Impersonator 406. It is a 5.7 rod 406, 9.5 cr, unmolested 175cc iron vortec heads, airgap intake, and a 230/230 .480/.480 cam. It made 428hp @ 5,000 and 525tq @ 3,500...WOW. Im half tempted to through hyper slugs and arp rod bolts in my 400 and duplicate this build. Of course I want to get greedy and do a little bit more to it. Such as: how much more duration could one go without sacrificing that amazing tq, a little more lift can never hurt right? what about aluminum vortecs and more compression, will larger port vortec heads actually cause a loss in torque do to slower velocity's?

I'm just exploring my options, 500+ lb/ft from a small block just makes me drool. Thanks, Kurt
