The Chevrolet Silverado 454ss 1990 mod in Grand Theft Auto 5 is designed to allow players to use and drive the classic 1990 Chevy Silverado 454SS pickup truck within the game. As indicated by the model name, this truck is equipped with a 454 cubic inch (7.4L) V8 engine. 

In real life, this engine provides the Silverado with approximately 230 horsepower and 385 ft-lb of torque, giving it substantial power and acceleration for a vehicle of its size, age and type. It's highly likely that these real-world specs are mimicked in the game, though the exact performance can sometimes vary depending on the precise programming of the mod.

This half-ton pickup truck has a distinctive muscular appearance, mirroring the real life Silverado's boxy, rugged look that was standard for 90's era Chevrolet trucks. The interior of the modded vehicle is likely to be detailed and accurately designed, reflecting the comfort and spaciousness of the real-world counterpart.

This particular mod would appeal to players who enjoy driving classic American pickup trucks in Grand Theft Auto 5, or who have a specific fondness for the iconic Silverado series.
