eBay Here's one version of an ultimate sleeper car for the Mopar enthusiast: a 2006 Chrysler 300C with a custom-built 7.0L stroker Hemi, dynoed at 650hp. The owner paid $16K to have the stroker professionally installed and tuned, with forged internals, blueprinted cams etc., and the motor has already done 40K trouble-free miles over 8 years. The performance is nothing short of spectacular, and the owner is selling only after buying an Aston Martin.
The motor build was done by the guys at Stack Performance in CA: all Mopar enthusiasts. So it is beautifully done, and runs like a dream. The power is insane and addictive.
This is not a car for a novice, so please don't think about purchasing it unless you know how to handle serious power. The performance is blood-curdling, and the traction control has been turned off to allow all the burning rubber you want. This thing can chirp or smoke the tires at freeway speeds! Comes complete with Predator tuner. Obviously, serious, committed buyers only. Mechanic inspections welcomed. This is a beautifully done, squeaky clean pro install and tune. The builders said it could be squeezed to 700+hp with a slightly different cam than the blueprinted one that's already installed. We asked the owner why he left on the original engine cover (with 6.1L) on it. It's a sleeper!, he laughed. OK, whatever.
The original SRT8 motor had developed a serious issue at around 80K, when one of the bearings let go and damaged the block. The owner decided that if it was going to need a new engine, he'd lay out for a custom build, so Stack picked up a replacement short block to use as a core, and completed the build on that. The build sheet is pictured.
This is a truly amazing vehicle, and about the best power-to-dollar ratio you can possible find. Try finding this much power for this little money anywhere else!
