Recently, Scottie-D TV had the opportunity to take a tour of the Lingenfelter Performance Engineering (LPE) shop to get a closer look at the 427 engine package they offer for the 2014-2015 Chevy SS sport sedan.
With a 415 hp/415 lb-ft. version of the C6 Corvette LS3 under the hood, the sky is the limit in terms of what you can do for your SS from LPE. Having getting this customer car in not too long ago, LPE performed a baseline test in its bone-stock format, just to see where the car was at before any mods were performed.
With several performance packages available from LPE, including two that bring a Magnuson supercharger along with them, there are plenty of avenues Chevy SS owners can take with their cars.
Here’s the complete 427 cid. recipe from LPE:
