The LY6 is 365HP and 383ft-lbs.
If you dump a cam in it you easily move it into the 440 hp and 460 torque range. This outstrips the 454 Vortec for a less money and you get the 6L80 with 6 gears or the 8L90 with 8 so the fuel mileage is far better.

The time of the old iron block smallblock and big block GM engines for daily drivers has come and gone for the most part.
They are antiques and worth restoring if that's what you want. If you want a reliable daily you want an LS.

Other than late model parts, another reason I don't go there....

Really bizarre behaviour on the part of a business that's purporting to make money. It wouldn't be shocking to find out they're getting cash infusions from IBM (Italian Businessmen) in Philly, Jersey, Utica-Rome, Albany, or Brooklyn.
