Week To Wicked’s 625 Horsepower Heart

Horsepower Heartbeat

What makes a muscle car? The look? The sound? How about the power? We’d say all three, but it’s the power and the unmistakable staccato thump of a pushrod V8 that ultimately personifies a muscle car. As April 18th – D-Day for CPP Week to Wicked presented by Super Chevy and Axalta– draws rapidly closer, we wanted to give you a peak at the 625-horsepower monster that we’ll be swapping into our 1967 Chevelle.

The Engine

The story of this LS begins at BluePrint Engines’ Kearney Nebraska headquarters. It is there that the makings of horsepower begin. While BluePrint has roots in all manner of performance engines, this GM 427 LS series is the pinnacle of their performance lineup. The block, which is a Chevrolet LS3 casting, is treated to one of BluePrint’s stroker crankshafts, SCAT rods, and a custom piston jointly designed with Mahle. The piston was specifically engineered for this long-stroke, big-cube LS, and enables it to remain stable in the cylinder bore at high rpm. Topping the mondo shortblock is a set of BluePrint’s own LS3-style cylinder heads with big 2.165-inch valves and springs ready to accept the .624/.624-inch 239/255-degree hydraulic roller cam. The engine being supplied for the Chevelle is fully dressed and even comes with an ECU programmed with a custom calibration that was tuned in-house by BluePrint. We took a trip to BluePrint’s dyno room and watched them make a pull on this wild motor. It did not disappoint. Check out the video for an early glimpse of this LS in action, and make sure to check back during Week to Wicked for what is sure to be a heckuva automotive adventure.


What is CPP Week to Wicked, Presented by Super Chevy and Axalta?

It all begins the morning of April 18 when our stock 1967 Chevelle will roll into Super Chevy’s Santa Ana Tech Center for a full teardown and rebuild. We’ll be pulling the car down to its bones, replacing steering, suspension, powertrain, drivetrain, and just about everything else you can possibly imagine; all with the goal of bringing the performance of a 1967 Chevelle up to par with modern muscle cars. It’ll be a mad rush till the very last seconds of our timeline. And if that wasn’t enough, immediately following the build, we’ll be driving the car on a 1,000-plus-mile road trip to prove its road readiness. We’ll be hitting the dragstrip, the engine dyno, and a few local cruise-ins (to be announced at a later date). Learn even more about the project HERE, or read the stories below.
