GS option differences from base LT4
WHere can I find authoritative information?
"The 1996 version of the Grand Sport evokes memories of its predecessors with its exclusive Admiral Blue Metallic paint, white stripe, and red "hash marks" on the left front fender. Chromed "Corvette" emblems on hood and fuel door, 17" five-spoke black aluminum wheels, black brake calipers with raised bright aluminum "Corvette" lettering, and perforated Sport bucket seats available in Red/Black combination or Black options with emroidered "Grand Sport", distinguish the Grand Sport for 1996. Grand Sport Coupes are outfitted with P275/40ZR- 17 (front) and P315/35ZR-17 (rear) tires, and special rear fender flares cover the extra-wide rear rubber. Convertibles roll on P255/45ZR-17 (front) and P285/40ZR-17 (rear) tires. There will be limited production for Grand Sport models, each carrying a unique serial number.
The 1996 Corvette Grand Sport has the horsepower to support its racing heritage. A new 330-horsepower LT4 small block V8 is standard on Grand Sport (optional on all other Corvette models). A further development of the powertrain technology introduced on the LT1 V8 for 1992, the muscular new LT4 has the performance advantages of high-flow aluminum cylinder heads, larger hollow-stem valves and higher load springs, a more aggressive camshaft profile, revised pistons with a 10.8:1 compression ratio, a new fuel injector that increases fuel flow, and friction-reducing roller rocker arms. The LT4 engine assembly is bolstered with an undercut and rolled fillet cast iron crankshaft, steel camshaft and water pump gears driven by a roller chain and premium head gaskets.
The LT4 stands out from its small block siblings with unique appearance features, including a red inlet manifold, red spark plug and coil wires, red "Corvette" lettering on the manifold covers and red "Grand Sport" lettering on the throttle-body cover. Models equipped with the LT4 engine have an 8000-rpm tachometer with a 6300-rpm redline. The High Output LT4 is available only with a 6-speed manual transmission"
