Stroker small blocks - what intake?

All those sound fine, except the intake and carb. See if you can borrow a larger carb. Either an 850 DP, or an 870 Vaccum Demon or Avenger..The VS may be easier for your kind of racing...I would also suggest a larger plenum intake, and either an open spacer, or none at all. The Victor might work well on your setup with a vaccum 870. Another choice would be a cleaned up M1 single plane with an open spacer.
