We start with seasoned hand picked cores, cylinder walls are sonic tested and maglifluxed. All deck surfaces are square decked using the BHJ blok true fixture, this allows us to equally machine the left and righ side deck heights parallel to the crank centerline. Cylinder bores are bored using the BHJ bore true fixture. this relocates the cylinder bore centerline to be exactly centered over the crank centerline. Main bearing bores are align honed to the correct size and fastened with new ARP main bolts. Cylinders are honed with torque plates. All rotating assembly parts are balanced within +/- 2 grams. All engines are professional machined and built right here in our shop. We build honest horsepower the right way.
