We built a TORQUE KING, using some classic Chrysler engineering. If you've ever wondered what happens when you combine Chrysler's fabled long ram intake manifold design with some modern engineering, here's your answer: 590 horsepower @ 5000RPM and 700 lb-ft of torque...@ 3000RPM. Yes, 3000. And it carries that torque a significant way through the rev range. Anyone familiar with this manifold knows Chrysler designed it to move heavy cars quickly. These specially, factory "tuned" manifolds were supposed to deliver something of a supercharging effect, boosting low-speed torque significantly. They worked back then, and obviously, still do. And just to be clear, when we say supercharging effect, that's all we mean, because this engine is all natural. No power adders other than 505 cubic inches of raw, MOPAR BB power. As for the build itself, it's one of our "basic" 505 inch strokers with a few key mods. First off, is the use of Edelbrock Performer RPM heads instead of our proprietary TNT BB castings. While the Eddy's don't flow as well as ours, their runner design matches the long ram manifold properly. Next, is the fuel injection. Yes, fuel injection is an option on all our BB packages, but this one is special in that we used a Holley Terminator X Stealth system to tune two Holley throttle bodies like they were port injection. This was necessary because the long ram manifold, while extremely effective at doing its job, also wreaks havoc with carb signaling which meant we had to do some intense tuning to get it to work right. And work, it does, as you can plainly see. Another cool thing about this engine is that it's being dropped between the fenders of a classic MOPAR and will be street driven regularly. Should be lots of fun. For a rundown of our 505 package, visit https://www.performanceinjectionequipment.com/SHOP #!/Big-Block-493-Stroker-Street-Performance/p/96506794/category=27035713
