The 350/290 Deluxe uses cast aluminum pistons, has an 8:1 compression ratio and has a recommended redline of 5300 rpm.

The LC9 crate engine is an LS-series Generation IV motor that displaces 327 cubic inches. Despite its smaller displacement as compared to the 350/290 deluxe, it has a higher power output than the larger engine at 320 peak horsepower.
