A 5.3 in an avalanche is a joke. It's the heaviest light duty 1500 GM makes.

So, the GM "insiders" say the intake is DONE at 5600rpm's huh? So much for retaining that crate motor warranty putting in new valve springs

Its called a 327 because of the 327 hp rating. It's a stock bore 5.3, probably with the L33 pistons and a bit better cam. It's a waste of money basically.

Magazines are out to make money, through advertising. They also need to be weary of potential lawsuits
