Every year, Chevrolet uses the SEMA Show to unveil the best it has to offer for go-faster junkies. After revealing the 2017 COPO Camaro and two drag racing prototypes of the Camaro SS, Chevy now ups the ante with the 2017 Chevrolet Performance catalog. And yes, two all-new crate engines are in the offing.
The first of the lot is the LT376/535. Based on the 6.2-liter V8 in the Camaro SS and Corvette Stingray, the crate engine makes use of a high-performance camshaft and CNC-ported cylinder heads. Marketed as a racing engine, the LT376/535 boasts direct injection and 535 horsepower at 6,300 rpm from an 11.5:1 compression ratio. 470 lb-ft (637 Nm) is available at 4,600 rpm.
Then there’s the SP350/357. Dubbed the “Affordable Performer,” the mill was designed with power, durability, and value in mind. Based on the 350 HO, the 5.7-liter V8 develops 385 naturally aspirated horsepower at 5,600 rpm and 405 lb-ft (549 Nm) at 3,600 rpm thanks to high-flow Vortec cylinder heads.
Depending on what you want to do with it, the SP350/357 crate engine has a nominal compression ratio of 9.6:1 and it can be had in three flavors: Base, Deluxe (features intake manifold and so forth), or Turn-Key (includes starter, Holley 770-cfm 4-barrel carburetor, distributor, the whole nine yards).
Also new for 2017, Chevrolet introduces the LT1 Connect & Cruise and E-ROD packages. For the first of the lot, the wet sump LT1 V8 is matched with the GM 8L90-E eight-speed automatic transmission. The LT1 Connect & Cruise E-Rod package, on the other hand, takes things that little bit further.
In addition to the aforesaid, E-Rod adds catalytic converters and other emissions-related equipment to make 1996 and earlier vehicles CARB-compliant in California. Even with all those nannies on the menu, the E-Rod package lets the LT1 sing its burbly song with the intensity of 455 horsepower at 6,000 rpm and 465 lb-ft (630 Nm) of get-up-and-go at 4,600 rpm.
Last, but not least, the 8L90-E eight-speed automatic joins the SuperMatic 4L75-E and T-56 Super Magnum as an option for the LT1 and LT4 crate engines. Adapted from the 8L90 available in the Camaro SS and Corvette Stingray, the 8L90-E features four gearsets and five clutches. It’s also a packaging marvel, fitting in the same space as GM’s six-speed auto.
