Engine Selection For The Pro Street Corvettes
Pro Street Corvettes has four separate engine configurations in use for the Corvettes we produce with each model offering an entirely different driving experience. Each Pro Street Corvette is designed from scratch to fit the needs, wants and the budget of our clients. These engines below are the 'starting point' of the actual powerplant used to power your Corvette. Each of these Chevrolet high-performance engines will be tailored to fit your driving style from mild to land-speed record cars for the Bonneville Salt Flats to drag racing on the eighth-mile and quarter-mile drag strips.
The Beast comes standard in our Corvettes equipped with a 600 H.P. all aluminum Retro ZL-1 427ci Chevrolet
engine equipped with an 850 cfm BLP Products performance carburetor, and a 3 stage dry sump
oiling system. This is the basic engine for The Beast, call it a building block to the type of Corvette you desire to own and drive. Upgrade options include alternate piston & camshaft combinations, various induction configurations such as carburetors, electronic fuel injection, mechanical fuel injection, superchargers, turbochargers, and 71 series blowers. These engines will make your Pro Street Corvette turn heads on the street, at the car shows, and especially at the tracks should you decide to race your Corvette.
"The Son of The Beast"
The Son of The Beast engine combination comes standard equipped with a 500 H.P. all aluminum 427ci small block Chevrolet engine equipped with an 850 cfm BLP Products performance carburetor and a 3 stage dry
sump oiling system. This is the basic engine for The Son of The Beast, call it a building block to the type of Corvette you desire to own and drive. This engine is for those that prefer the scream of a small-block Chevy engine when you romp on the accelerator.
Upgrade options for The Son of The Beast powerplants are similar to those of The Beast and they include alternate piston & camshaft combinations, various induction configurations such as carburetors, electronic fuel injection, mechanical fuel injection, superchargers, turbochargers, and 71 series blowers. These engines will make your Pro Street Corvette turn heads on the street, at the car shows, and especially at the tracks should you decide to race your Corvette.
Alternate Engine Choices
Pro Street Corvettes also offers two other engine options of the high-tech LS series of Chevrolet high-performance engines. These engines are available to those desiring a more docile engine with smoother idling characteristics than the big-block Chevy or small-block Chevy engines we offer above. This is not to say that these are “stock” engines or low performers, just ask the driver of a rice burner who just got beat by an LS series engine.
LS3 Chevrolet Engines
The LS3 was introduced as the Corvette's new base engine for the 2008 model year. It produces 430bhp @5900rpm and 424lb-ft @4600rpm without the optional Corvette exhaust and is SAE certified. The block is an updated version of the LS2 casting featuring a larger bore of 4.06 in creating a displacement of 6,162 cc (6.162 L; 376.0 cu in). It also features higher flowing cylinder heads sourced from the L92, a more aggressive camshaft with 0.551" lift, a 10.7:1 compression ratio, a revised valvetrain with 0.24 in offset intake rocker arms, a high-flow intake manifold and 47 lb/hr fuel injectors from the LS7 engine.
The L76/L92/LS3 cylinder heads use 2.165 in intake valves, and 1.59 in exhaust valves. Improved manufacturing efficiency makes these heads cheaper than the outgoing LS6 heads, and severely undercuts aftermarket heads. The large valves, however, limit maximum rpm - 6000 in the L76 (with AFM), and 6600 in the LS3 (with hollow stem valves).
In addition to the above, a dual mode exhaust package with a bypass on acceleration is available. The dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. The system is similar to the C6 Z06, but uses a 2.5 in diameter exhaust compared to the Z06's 3 in. Power is boosted to 436 hp and 428 lbf•ft with this option.
LS9 Chevrolet Engines
The LS9 RPO code was originally used on 69 and up Chevy trucks, available in 2 and 4 wheel drives, Blazers, Jimmys, and Suburbans. The original LS9 was a 350 cu in V8. The Gen IV LS9 is a supercharged 6,162 cc (6.162 L; 376.0 cu in) engine, based on the LS3; the LS7 block was not used due to the higher cylinder pressures created by the supercharger requiring the thicker cylinder walls of the LS3. Cylinder dimensions are now 4.06 in bore and 3.62 in stroke. It is equipped with an Eaton four-lobe Roots type supercharger and has a compression ratio of 9.1:1. Power output is rated 638 bhp @6500rpm and 604 lb•ft @3800rpm.
While the LS series of Chevrolet engines do not present alternate configurations each of these engines are powerhouses on their own.
Fuel Injection Option:
Pro Street Corvettes offer a high performance mechanical or electronic fuel injection option at an
additional cost on all engines but the LS series.
