LSX Bowtie Block
GM Performance Parts has collaborated with NHRA legend Warren Johnson to create the new LSX Bowtie Block, based on the Gen IV small-block and designed to be the ultimate high-performance LS engine block. The LSX brings race-level technology to the street at an affordable price, enabling engine builders to use traditional displacement-enlarging techniques. Highlights include six-bolt billet mains, a thick deck for maximum clamping force, thick cylinder walls for increased bore diameter and excellent water flow, and a true priority main oiling system for standard hydraulic-roller lifters. The LSX comes with a 9.26-inch semifinished deck height and a 9.70-inch tall-deck version-allowing for a 4.50-inch stroke-is on the way. The ready-to-hone bores measure 3.99 inches, with a capacity for 4.250-inch bores. Put 'em together and displacements from 364 up to 500 ci are possible. It also accommodates all Gen III and Gen IV cylinder heads, oil pans, and oil pumps, and can be built with either fuel injection or a carb. The LSX Bowtie Block will be available in March 2007, with LSX-specific heads, intakes, and cams to follow.

Early-Nova Mini Sub-Frame Kits
Classic Performance Products' new bolt-in Mini Sub-Frame Kit promises better ride quality and improved road feel for '62-67 Novas. According to CPP, eliminating the bind of the factory strut rods allows for proper alignment and creates smoother-working lower control arms. The original Nova camber adjustments are used, along with an added forward caster adjustment for hassle-free alignment. The crossmember ties the framerails together, providing additional strength. This kit includes tubular upper and lower control arms, a 11/44-inch steel crossmember, four alignment cam kits, low-friction bushings, and all needed hardware. The Mini Sub-Frame accommodates both factory sway bar and aftermarket sway bars, and kits with springs and shocks are available.

Twist & Shout
Timing Twister
With its new Timing Twister, MSD is looking to give owners of Gen III/IV-powered rides unprecedented control of their powerplant's ignition timing. The control module has four rotary dials that enable the user to advance the timing curve (up to 9 degrees in 1-degree increments), set up a step retard, or, when paired with the optional MAP sensor, set a retard based on boost pressure (up to 30 degrees). The Timing Twister also features a setting for a wire-activated step retard (primarily designed for use with nitrous). The system plugs into the OEM wiring harness, and a simple twist of a dial returns it to the factory ignition curve.
