Russ,
High two's at the rear wheel seems about right for what you describe. You can make a lot more by following what we have been talking about. What CJ describes sounds about right for his friend's setup as well.
However, I would prefer what I described, because it makes torque down lower, and still makes about the same HP, but at a lower RPM. The peak HP is 524.7 @ 5500RPM, and 541.0ft-lb @ 4600. It has 508.7ft-lb @ 3600RPM!!! This thing is a brute, and you don't have to rev it as much, making it more streetable (I have a copy of the dyno sheet on it). The main difference is in the RPM air Gap dual plane intake matched to the Vic Jr heads. This combo takes advantage of the increased cubes in the stroker (408) without jumping things as far up in the RPM range as the single plane Vic jr intake. This should get you to right about where you want at mid-400s RWHP. By the way, you can get a version of this setup ready to drop in and run from Keith Craft for about $5600, but for that price you get the cast crank. However, you can upgrade it as well. Check out his website http://www.keithcraft.com/new_site/index.html If you want a higher revver, go with something like CJ is talking about.
