Backing up all that brute force is a touch of modernity: a Richmond six-speed with a 3.27:1 First and 0.74:1 Overdrive. A McLeod Street Twin Dual Disc clutch lives within the Lakewood bellhousing/scattershield. With a 4.11-geared, Currie-axled Dana 60 out back, that makes for low-rpm cruising that won't wreck your hearing. Meanwhile, the short First helps launch Lewis to 11-second quarter-mile times (quickest is an 11.78-illegal with no rollcage, by the way) at 122 mph.
Perhaps surprisingly, there's not much complicated going on underneath to help the big X hook. Those fat skins help, as do the Super Stock leaf springs (with two additional leaves on the right), and the Dave Walters-fabricated traction bars replacing the pinion snubber. Polyurethane bushings all around, Koni shocks on all corners, and Mopar Performance torsion bars complete the chassiswork. That's not much for an 11-second street-driven thrill ride.
Forewarned is forearmed. Otherwise, you'd never know what hit you.
