New low rise TB adapter for 4 BBL intake

While thumbing through this month's Muscle Mustangs magazine, I noticed a company that had come up with a new single plane intake for Cobras. They had built an elbow that utilized the stock twin bore throttel body, and placed it out front. http://www.sullivanperformance.com/Y.../tbadapter.htm

This elbow bolts in place to a 4150-style flange. What I was wondering is if the stock Cobra twin-bore throttle body could be made to work on an LS1, and this might allow people using the GMPP or Edelbrock Victor Jr. intake to run those manifolds without cutting their cowls, and fit under a stock hood without problems. What do you guys think?

I was just wondering if this could be made to work, as far as the electronics go. How much HP is the Cobra TB worth?

The ford IAC is not the same style as a GM iac motor.

Ford is a duty cycle driven unit, where the GM is a stepper motor.
