Well it's the black sheep of the GM power plants. If it doesn't have cubes, it won't perform is the common logic for a large % of guys who build these trucks. I don't think it's a far stretch to believe this guy does have the fastest stock 4.8L, at least in a FS chevy. Till someone claims otherwise and is willing to prove it, it is what it is. People can always lie or keep their times to themselves.
In this hobby, it's mostly based on goals. Whether it's winning races, going faster, or being the first at something.
To each their own.
