|Jonathan Capizzi of Holland, MI made the long haul down to Ohio Valley Dragway in Kentucky for the “Turkey Bash 2K19” event. In testing for the race, Capizzi shocked the world when he set a new stock bottom end (SBE) record for LS engines with his insane 4.506 @ 155.70 mph pass!|
|Starting with a Gen IV 5.3L pulled from a 2011 Suburban, Jon outfitted it with a Garrett Gen 2 88mm turbo, a custom ground Baker camshaft and 799 casting heads that he hand ported himself. Topping the engine off with a Holley EFI system, including a Dominator ECU, Holley Hi-Ram intake manifold/fuel rails, a slew of Holley sensors and methanol fuel to make this one rowdy combination!|
For those questioning the “SBE” moniker, you can be assured that this 5.3L is all GM. Jon says that even the short-block fasteners are OE only relying on aftermarket hardware for the cylinder heads and balancer bolt.
Congratulations to Jon and the Capizzi Automotive team on this record and continuing to lower the E.T. even further.
