TPIS makes the miniram, which is basically an LT1 manifold suitable for
conventional SBCs.  AS&M makes some large-tube runners.  Accel makes
Large-Tube Runners usable with a stock plenum, a high-flow base, and they
also make the SuperRam plenum/runners(which I just installed ~2 weeks ago).
 Edelbrock makes a base and runners, SLP makes runners.  None of it is
cheap, really.
