The Vortec 5300 engine: loved by all. Whether it be by the practical guy for its reliability & surprisingly good fuel economy, or by racers/Sloppy Mechanics for its junkyard price tag & ability to hold obscene amounts of power with a little boost. Nearly everyone can agree that these engines are fantastic.
However, in the case of the AFM (Active Fuel Management) variants — such as the LY5 found in Dante’s 2007 Chevrolet Tahoe pictured here — lifter failure is a near certainty at some point. While the practical guys may just want it fixed back to factory working order, the gearhead views lifter failure as an opportunity to improve, and pick up a little lope in the process… obviously, Dante is the latter.
Louis has this LY2 under the knife to bring it back to life and better than ever! This round, he’s installing a COMP Cams camshaft & supporting components, OEM GM LS7 lifters, Melling Performance Parts engine oil pump, C5R/C6R timing chain, and all the miscellaneous OEM GM bits-and-pieces necessary to delete the failure-prone AFM system. Once the mechanical work is wrapped, she’s hitting the rollers to get dialed in by Vlad via HP Tuners.
