As per Summit's web site,

"Edelbrock's Torker II intake manifolds feature a single-plane, low-rise design that can give you top-end horsepower without affecting the mid-range. What Edelbrock did was increase the plenum volume and alter the short-side radius of the runners, to give the air/fuel charge a straight shot at the intake valves. That straight shot produces a potent power build from 2,500 to 6,500 rpm."

So unless you want to build a car that's comfortable in the above RPM range, the Torker II may be a good item to list on Craigslist or E-Bay.

The Performer RPM seems to be a great manifold for most stock to moderate SB builds.

Good Luck,
