Quote: And maybe that 337 has more cross section between the plenum and head than the Super Victor? (tapered to same port window obviously) I would think that could be part of it too (505 CID, 7300 rpm, = flow needed).
I'm leaning towards that explanation, considering the similar Stage VI intake that Bobby (streewize) referred to above had such a large plenum and significant taper in the runners. On a 440, it made big HP, but had a noticeable dip in the torque curve below the torque peak.
I like to see how the MP intake and the Super Victor's torque curves compare across the RPM range, but noticed Andy's "no dyno curves available" reply.
