About “Z28”
My work in progress street/track car. I rebuilt the engine for a gain of roughly 100hp and updated the interior with 4th-gen seats, console and all new gauges. The next year I did the rest of the driveline retrofitting a T56 6-speed with a new flywheel, clutch, shifter, driveshaft and 4.10 gears. I also rebuilt the front suspension with poly bushings and lowering springs, and wedged the subframe with solid body mounts and welding in connectors. I also upgraded the brake system with bigger rotors and converted the rear from drum to disc. To try and get the tires to hook I went with drag radials and adjustable traction bars. I also upgraded the fuel system and ignition. After I broke the rear end at the track I upgraded that also.
Next comes some body work at some point. Wheels are also on the list, and probably a shot of nitrous, because truth be told, I'm stupid like that.
