Madkaw, we'll probably forget about this by the time you get to the dyno but please DO resurrect this thread and post your results.

Thanks.

No experience with the trips but just looking at it the triples manifold has 6 short, equal runners.

EXACTLY! Triples have dedicated runners to each cylinder. This is an inherent advantage over SUs because of better mixture distribution between cylinders and a stronger signal for resonance (harmonic) intake tuning.

There are also less pumping losses because of the fixed venturi design, so there are performance benefits to Webers outside of WOT operation. Correctly tuned, they will get better fuel mileage as well.
