As i've posted longk ago, the Torker I can do very well with a Plenum porting(hogout) using a drill press and rasp to unshroud the runner ceilings from/to the Spreadbore openings.

Becomes a low 10 sec manifold for under 5-Lbs metal, and supports 9.0:1 Street use too.

Otherwise the 68-70's Factory iron Manifold is good enough for Street use, having the air-inhale isolation (5-7, 2-1, 4-3, 6-5) that the single-planes lack.

I hope the Speedmaster dual-plane is "all that" the Factory Iron is, with bonus being the Fuel Injection bosses.

Airhorns; itsa all true. I figure the trumpet opening is best: inlet edge is 90* from the air flow, like a musical trumpet but squat.
