For 2017 Chevy wants to enhance their factory-built Camaro racecars for NHRA's Stock Eliminator classes. Chevy unveiled the 2017 COPO Camaro with a few added surprises at the 2016 SEMA Show in Las Vegas. The COPO LT engine starts with Chevy's production-based 6.2 LT block, stuffed with a hotter cam, all-forged rotating assembly, CNC-ported heads, and a Holley Hi-Ram intake. Taking things a few steps farther is the revised COPO 427, which uses the stouter LSX iron cylinder block. Because this is an LS-based block, available as a bare block and even semi-finished for you to do final machining, all of the Gen IV heads, cranks, oil pans, cams and accessories still bolt on it in case you're thinking of building a similar engine for your own racecar.
The COPO 427 includes an all-forged rotating assembly, high-flow LS7-style heads, and a Holley Hi-Ram intake able to produce high RPM power. The last engine option, returning for 2017, is a 350ci supercharged LS engine. All engines are backed by an SFI-approved ATI TH400 three-speed automatic transmission. These engines are also available individually outside of the COPO Camaro program should your project/race car necessitate a bump in power.
