Description: Are you looking to build an awesome resto-mod with great throttle response and all the power you can realistically put to street tires? How's 680 horsepower and 560 torque? Your ride is going to be a cruiser, so it needs to have street manners, be utterly reliable and low maintenance. Chances are your hood will be up a lot at car shows, so the engine needs to look great. You are looking for Plug & Play so as to avoid any installation and fabrication nightmares. Once finished, you have no intention of ever selling your dream ride, so the engine must be built to last. To get your project finished, the drive train can't break the bank. Look no further. Borowski Race Engines has what you want. The simplest solution is usually the best solution. That means naturally aspirated; something we can do comfortably with a hydraulic roller cam.
