Behind the engine is a Tremec six-speed, perhaps the most popular of the new-generation gearboxes. The use of this unit required the tunnel be raised and the shifter location changed to make it fit. The old school 8.75 SureGrip rear was left in place, complete with a 4.30 ring that lets the quick-winding engine get underway. Tom says making the Viper Challenger a reality took over 1,000-plus man-hours, and the cost...well, he didn't answer that question.

So, what did Tom Brown end up with, besides a great ride (with just 200 miles on it since completion), to take on the 2005 Power Tour? In addition to big smiles and this magazine story, the car averaged 20 mpg on the highway. Coupled with the convertible comfort, big horses, and curb appeal, this is one date we think anybody would take out on a summer evening.
