Total Cost Involved and Jim Reese, owner of Classic performance parts, are in cahoots to build the sleekest street-driven '70 Nova. Jim provided the Nova and TCi provided its r&D team's collective talent in the construction of their own brand of a four-link rear end specifically for the thirdgeneration Nova. like any good manufacturer, TCi offers its rear end kit with standard parts and optional upgrades as well. Before we move on, let's take a look at what they are.
The standard rear end in this kit is an all-new 58 1/2-inch rear with new 31-spline axles from Currie Enterprises that can accommodate some wickedly wide wheels. The optional gearing is as follows: 3.00, 3.25, 3.50, 3.73, 3.89, 4.11, and 4.56. Posi-traction is also another available option. A Panhard bar is supplied when a 9-inch inch rear is used, and a track bar is supplied when a Chevy rear is used.
Brakes range from 12- and 13-inch Wilwood drilled and slotted zincwashed rotors with optional painted or polished calipers. Standard GM 12-inch smooth rotor and GM calipers are also available. Drum brakes and the backing plates are another possibility. All brake kits have an internal parking brake assembly similar to the Corvette's.
Four-link options include billet adjustable coilovers (manufactured by TCI) or polished billet coilovers, chrome bars with chrome coilovers, polished stainless bars with chrome shocks, or an antisway bar (also with chrome option). If coilovers are not desired, ShockWave airbags from Air Ride Technologies can be ordered.
Our goal for this article is not to cover every nut and bolt of the rear clip install. We really wanted to take it out to the endless blacktop at the California Speedway in Fontana, California, and thump it till it cried for mercy. The end goal is not the install itself, but rather does it work? Can it handle, and what are the results?
