If you don't want to spend the money on such an extensive undertaking, read on for some cost-effective upgrade options for more power. This is important for many reasons, but it also requires a significant amount of money and time.Įngine swaps can certainly give you the upgrade you're looking for. Whether you have a Chevy Silverado or another vehicle type, you must first upgrade your 5.3 Vortec if you wish to experience max horsepower. Getting More Horsepower From The 5.3 Vortec This combination of the engine and transmission is available in higher trims. The first year in which the small V8 engine can be paired with an automatic transmission is this. The 8-speed can be used with the small V8. It can also be mated to an 8-speed automated transmission. This prevents any aftermarket companies from tuning it to produce more power. GM has secured the ECU/computer for the new truck. The stock power output remains at 355 horsepower. The truck's V8 engine stock is a 5.3-liter V8. It will never surpass the alpha-numeric legends L88, DZ302, L88 and LS6. The new gen-5 version of the L83 could change this. Most Chevrolet enthusiasts don't like the original L83, which is rated at 205 horsepower. The L83 xfire was the predecessor of the L98 Tuned-Port motors. Chevrolet's naturally-aspirated crossfire injection system used a trick cross-ram intake design to feed a pair of single-hole throttle bodies. The L83 designation refers to the direct-injected, direct-injected 5.3L, direct inject 5.7L. The regular unleaded gasoline produces 355 horsepower 5,600 RPM and 383 lb-ft, and a 4,100 RPM range.

Let's use a 2016 Chevy Silverado 5.3L V8 as an example. The Chevy Silverado is a popular vehicle that uses the 5.3 Vortec engine family. The performance of both the Gen III and Gen IV models is impressive, especially when compared. While it is possible to argue that the current top choice in performance is due to availability and price, the real issue is the actual performance. Vortec and LS versions are the current best choices for performance in the 5.1L LM. The DI L83 mill was equipped with a number of highly capable LS-waps. For those with tight budgets, the 5.0L LM7 was a reliable LS-swap device. We were skeptical when they first appeared on the salvage channel. It produced 310 horsepower and 335 lb-ft torque. The Vortec's 5.2L Vortec engine design was phased out. The Vortec LM7 original produced 270 horsepower, and 315 lb-ft torque. Let's continue on to discover the best 5.3 Vortec HP upgrades for the typical LS owner. As such, all the modifications we look at today largely add horsepower gain by default.

It just requires running a short section of heater hose from the pipe tapped hole in the front of the manifold to the 5/8' hose nipple on passenger's side of the water pump. The modification is not to the manifold itself. Will also fit 1996 and later Vortec engines with some minor modifications. It also features four corner water outlets, dual distributor holddowns, includes a square bore carb adapter and gasket, and will work with a late model style water neck, alternator, HEI and air conditioning brackets. This manifold has provision for external water bypass. This manifold can be used on any Chevy V-8 engine utilizing 1996 and later Vortec (Gen 1+) cast iron heads or the Edelbrock E-Tec aluminum heads. This manifold is available in six different design configurations. This is our largest selling manifold with tens of thousands of them in use. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of squareīore carbs. The Cyclone is our lowest profile SB Chevy manifold and is also the only one that is street legal on pollution controlled vehicles.
